PHP variables are preceded by . . . . . . . .

Solution (By Examveda Team)

This question is asking about how you identify variables in the PHP programming language.
Variables are like containers that hold data in your program.
Think of it like a box where you can put different things inside.

To tell PHP which box you are talking about, you need to use a special symbol in front of the variable name.

Out of the given options, the correct symbol for PHP variables is: $
So the answer is Option C.

For example, if you want to store the number 10 in a variable named "my_number", you would write: $my_number = 10;
The $ tells PHP that "my_number" is a variable, not just a word.
