Explanation

The official remark says (D) follows grammatical rules: 'Three fives is fifteen' is acceptable because a multiplication statement may take a singular verb, and two subjects joined by 'and' take a plural verb, so 'Slow and steady win the race' is correct while 'Time and tide waits' is not. Note that the proverb is usually quoted as 'Slow and steady wins the race'.
