Explanation:
In the Logo programming language, the cursor is represented by a graphical object known as the "turtle". The turtle can be moved around the screen using various commands and can be used to draw shapes and perform other operations.

The turtle cursor in Logo is a key feature of the language and is often used to introduce programming concepts to beginners. The turtle can be controlled to move in different directions, turn at angles, and perform basic arithmetic operations such as addition and subtraction.

Logo and its features:
Logo is a programming language that was developed in the late 1960s to teach children the basics of programming. It uses a simple syntax and a graphical interface, making it easy to understand and use. Logo is known for its turtle graphics, which allow users to control a cursor called a turtle to create drawings and animations.

Logo provides a set of commands and procedures that can be used to control the turtle and perform various operations. These commands include moving the turtle forward or backward, turning it left or right, lifting or lowering the turtle's pen, and performing arithmetic operations.

The turtle cursor:
The turtle cursor in Logo is represented by a graphical object that can be moved around the screen. The turtle starts at a specific position, usually in the center of the screen, and can be controlled to move in different directions.

The turtle can be moved forward or backward a certain number of steps using the "FD" (forward) and "BK" (backward) commands. It can also be turned left or right using the "LT" (left) and "RT" (right) commands, which specify an angle of rotation.

Basic arithmetic operations:
Logo allows users to perform basic arithmetic operations such as addition and subtraction using the turtle cursor. This is done by specifying the arithmetic operation and the operands in the Logo command.

For example, to perform addition, the "+" symbol is used along with the operands. The turtle cursor can be moved forward by the sum of the operands. Similarly, subtraction can be performed using the "-" symbol, where the turtle cursor moves backward by the difference of the operands.

The name of the cursor:
In Logo, the cursor is commonly referred to as the "turtle". This term comes from the original implementation of Logo, where a physical turtle-shaped robot was used to draw on paper. The turtle cursor in Logo is named after this robot and is a central concept in the language.

Therefore, the correct answer is option B) Turtle.
