The right answer is C (Hail, king, for so thou art: behold, where stands/The usurper's cursed head:)
I believe the word horror would insert
the feeling of fear except disgust in this sentence.
The word “abomination” is defined as
the thing that causes loathing, disgust or the feeling of hatred. If the word
abomination would be replaced with the word horror in this sentence it would
insert the feeling of fear as the word horror represents the intense feeling of
fear, shock, or disgust.
The first answer is correct: "They suggest that the heat is stifling, giving the poem an oppressive mood".
The author begins the poem with the sentence cited above. The use of the expression "rend open" plus the use of the imperative mode, suggest some sort of desperation caused by the heat. That is why the author prays for wind (an unbeatable natural force) to come and defeat heat, ending the suffering.
