Question

which of the following is a valid variable name? !no
ame\ clas

Explanation:

To determine a valid variable name, we check the rules: variable names can't start with special characters (like !), can't be enclosed in quotes (as that would be a string literal, not a variable), and should follow naming conventions (letters, digits, underscores, no reserved words here).

• !no starts with ! (invalid).
• "name" is a string (not a variable).
• clas is a valid identifier (no special chars, not a string, follows naming rules).

Answer:

C. clas (assuming the options are A. !no, B. "name", C. clas)
