Question

Which sentence contains an error in punctuation?

Answer 1

I think so. No bs B seems right.

Answer 2

Answer: C.

Explanation: Sentence C is the one that breaks the rule for hyphenating compound numbers (i.e., numbers made of more than one word) from twenty one through ninety-nine. That rule does not apply to smaller numbers (like "sixteen" in option d) because those are already fused into a single word.
