Other options mentioned in the question:

A. Picture element:
- Also known as a pixel, it is the smallest unit of information in a digital image.
- A pixel is made up of three sub-pixels (red, green, and blue) and represents a specific color or shade.
B. Point:
- A unit of measurement used in typography and printing.
- One point is equal to 1/72 inch and is used to determine the size of fonts and other graphical elements.
D. Aspect ratio:
- The ratio of the width to the height of a display screen.

An audio output unit
An audio output unit refers to a device that produces sound or audio output. Here are some key points to understand about audio output units:
1. Can speak out small range of digits and specified words:
- Audio output units are capable of producing sound in the form of spoken words and digits.
- They can be programmed to speak out specific words or digits, such as phone numbers, addresses, or other predetermined information.
2. Is not used in information system:
- This statement is incorrect. Audio output units are commonly used in information systems to provide auditory feedback or instructions to users.
- For example, automated phone systems often use audio output units to provide instructions or read out options to callers.
3. Is very expensive and is thus not used:
- This statement is also incorrect. Audio output units come in a wide range of prices, depending on their complexity and capabilities.
- While some high-end audio output units may be expensive, there are also many affordable options available in the market.
4. Is normally used to give only background music:
- This statement is incorrect. While audio output units can be used to play background music, their functionality extends far beyond that.
- They are commonly used in various applications such as multimedia systems, gaming consoles, public announcement systems, and more.
In conclusion, an audio output unit is a versatile device used for producing sound or audio output. It can speak out a small range of digits and specified words, is commonly used in information systems, comes in a wide range of prices, and can be used for various purposes beyond playing background music.

As a student goes through his/ her academic career, attitudes about subject matter can be strongly influenced by a teacher's attitude about that particular student. If a student receives positive feedback from teachers then the student will probably try harder, which should translate into more academic success. If a student is being unfairly singled out because a teacher has a hidden bias, then success becomes increasingly difficult, and it becomes hard to keep that student positively motivated. However, an effective teacher should have the same attitude towards every student and cannot give differential treatment to different students.

Observation is an assessment tool which helps in evaluating student, both individually and in a group. It also helps teacher in understanding the students and making adjustment in the learning methods accordingly.

Statement (1) is correct: A bar magnet has two poles - a north pole and a south pole. The magnetic field is strongest near these poles.
Statement (2) is also correct: A compass needle aligns itself with the Earth's magnetic field, and it points towards the Earth's magnetic north. This indicates the presence of a magnetic field around the Earth.
Statement (3) is incorrect: In fact, a current-carrying solenoid produces a strong magnetic field inside it. The direction of the magnetic field can be determined using the right-hand thumb rule.

Methane has its molecular formula CH₄.
It is formed by one carbon atom and four hydrogen atoms. 
Hydrogen has its valency 1 and carbon being tetravalent needs four valence electrons to acquire noble gas configuration, where it shares its 4 electrons with four hydrogen atoms.
