A comparison of two numbers

A symbol used to represent a variable quantity
The initial point of an angle

The correct answer is: A symbol used to represent a variable quantity

A variable in mathematical expressions is a symbol that is used to represent a quantity that can change or vary. It is not a comparison of two numbers, a number being multiplied to a variable, or the initial point of an angle. Variables are placeholders for unknown or changing values in equations and expressions. Therefore, the correct answer is C: A symbol used to represent a variable quantity.
