31. The correct answer is B.

The original sentence begins with a comparison ("Unlike lions and

tigers"). However, the comparison drawn is between great cats

(lions and tigers) and hyoid bones of domestic felines. This is not

the correct comparison. We need a choice that draws the

comparison between great cats and domestic cats. Moreover, the

pronoun "their" is ambiguous: grammatically, it could refer to either

lions and tigers or hyoid bones. We need a choice that eliminates

the ambiguity.

The only choice to address all the issues is B.
