I believe C is your answer because I read it, just for a second and looked away and had to look back. There is a dangling modifier in C because it implies that the rabbit is "driving along the highway" when it (hopefully!) isn't. :)
Answer:
D
Explanation:
The easiest method is to substitute each option in place of tolerated. That being said, C doesn't make sense because it sounds wrong- "it was no longer already tolerated" isn't grammatically correct.
B doesn't sound right but there's (technically) nothing wrong with the grammar.
Tolerate means you ARE able to accept or endure something. Tolerable is the adjective version of that.
This can be tricky because you may think it's asking for the meaning of the phrase and not the word tolerable. It's only asking for tolerable.
That being said, A and B are the opposite meaning of tolerable- they mean you cannot endure it, which is the opposite.
D is the answer.
