Which of the following special symbol allowed in a variable name?
Answer: Option
Explanation:
Variable names in C are made up of letters (upper and lower case) and digits. The underscore character ("_") is also permitted. Names must not begin with a digit.
Examples of valid (but not very descriptive) C variable names:
=> foo
=> Bar
=> BAZ
=> foo_bar
=> _foo42
=> _
=> QuUx

Can identifiers start with '$' symbol also? I know that only the special symbol allowed is '_' (underscore). Is it correct?

The identifiers can start with the $ and _.
But they cannot start with the Digits like 0123456789.
