Identifiers must start with a letter or an underscore, followed by any combination of letters, digits, or underscores. So options A and D are invalid as they contain symbols other than underscores. Option B has spaces between the words, which is not allowed in identifiers. Option C, "finalGrade," follows the rules of an identifier and also uses camel case, which is a common convention for naming variables in programming.
