Quiz Practice:
C. _total
Answer: (C) _total
A C identifier may contain letters, digits and underscore, but it cannot begin with a digit.
2value is invalid because an identifier cannot start with a digit.
total-marks is invalid because the hyphen is not allowed in an identifier.
_total follows the basic identifier rules and is syntactically valid.
