Which of the following special symbol allowed in a variable name?
Answer: Option

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

=> BAZ
=> foo_bar
=> _foo42
=> _
