As we can see, the no. of electrons in the valence shell of oxygen (8) is => 6
In valence shell of carbon (6) => 4

In valence shell of  boron (5) =>  3 
Therefore, boron has the lowest electron in the valence shell. 

In the case of multiple images formed by a thick plane mirror, the brightest image is typically the first image. This is because the first image is formed directly by the reflection from the front surface of the mirror, where the most amount of light is reflected. Subsequent images are formed due to multiple reflections between the front and back surfaces of the mirror, which involve more loss of light and thus appear dimmer.

So, the correct answer is 2) first.

Fats and oils, including milk fat, can develop a bad smell and taste when they go through a process called rancidity. This happens when these substances are exposed to air, light, or heat for a long time. Here are the main points about rancidity:

• Rancidity occurs due to the breakdown of fats, leading to unpleasant odours and flavours.
• Oxidation is a key factor that causes rancidity, where oxygen reacts with the fat.
• Improper storage conditions, like heat and light, can accelerate this process.

To prevent rancidity, it is essential to store fats and oils in cool, dark places and in tightly sealed containers.

• Industrial Policy Resolution 1956 (IPR 1956): In accordance with the goal of the state controlling the commanding heights of the economy, the Industrial Policy Resolution of 1956 was adopted. This resolution formed the basis of the Second Five Year Plan, the plan which tried to build the basis for a socialist pattern of society.

• This resolution classified industries into three categories:

  • The first category comprised industries which would be exclusively owned by the state

  • the second category consisted of industries in which the private sector could supplement the efforts of the state sector, with the state taking the sole responsibility for starting new units

  • the third category consisted of the remaining industries which were to be in the private sector. Hence option 1 is not correct.

• Although there was a category of industries left to the private sector, the sector was kept under state control through a system of licenses. No new industry was allowed unless a license was obtained from the government. This policy was used for promoting industry in backward regions; it was easier to obtain a license if the industrial unit was established in an economically backward area. In addition, such units were given certain concessions such as tax benefits and electricity at a lower tariff. The purpose of this policy was to promote regional equality. Hence option 2 is correct.

• Even an existing industry had to obtain a license for expanding output or for diversifying production (producing a new variety of goods). This was meant to ensure that the number of goods produced was not more than what the economy required. A license to expand production was given only if the government was convinced that the economy required a larger quantity of goods. Hence option 3 is not correct.

• Headline inflation is the total inflation in an economy. The headline inflation figure includes inflation in a basket of goods that includes commodities like food and energy. Hence statement 1 is correct.

• Core inflation excludes food and fuel items from headline inflation. Since the prices of fuel and food items tend to fluctuate and create ‘noise’ in inflation computation, core inflation is less volatile than headline inflation. Hence statement 2 is not correct.
