Which of the following special symbol allowed in a variable name?
* (asterisk)
| (pipeline)
- (hyphen)
_ (underscore)
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
