B Correct answer
Explanation

In Java, identifiers cannot begin with a digit, making 52pickup illegal. Additionally, identifiers cannot contain special characters like #, which makes total# also illegal. The question is slightly flawed as it has two illegal identifiers, but 52pickup is definitely not legal.
