The correct option is D Nothing compares to the love and comfort you feel in your mother's arms.
A simple sentence is made up of only one clause, with one subject and
one verb. Option B contains a simple sentence, where the subject is "Nothing" and the verb is "compares", the infinitive phrase "to the love... ." is the object. Hence option B is correct. Option A contains a complex sentence, where the "as the evil ... ." clause is dependent. Option C contains a compound sentence, made up of two independent clauses. Option D also contains a compound sentence that is combined using the coordinating conjunction 'but'. Hence options A, C and D are incorrect.
