The correct answer is b. if i'm not mistaken, that rose is the reddest of all.
This is the correct answer because reddest is a superlative form and does not require MOST to be used.
I believe that your answer is the first option due to how late the crying is, and unlike in "The Tell-Tale Heart" where the heart is constant and represents the slow descent of madness, the cry of the cat only appears at the end.
The portion of the story where it shows the speaker's madness is actually his looking for and finding similarities in the second cat and wishing to kill it.
Hope this was helpful.
Let's define these types of clauses. Adjective clauses can serve as a multi-word adjective, basically. Noun clauses can serve as a multi-word noun, with a subject and verb, but remember, they are still dependent. Adverb clauses start with a subordinating conjunction. Now let's dissect this sentence.
"It is not right" independent clause
"to make a promise" adjective clause
"unless one is sure he can fulfill the promise" adverb clause
the answer is "one adverb clause and one adjective clause"
