The correct answer is Queen Gertrude is caught between her new husband and her son.
B is definitely incorrect because his father is dead so he cannot observe his conversation; C is incorrect because Gertrude believes Hamlet should blindly follow what Claudius has to say; D is incorrect because Hamlet hates Claudius.
This leaves us with sentence A - Gertrude has just lost her husband but she remarried immediately. Now, she is torn between her son whom she loves, and her new husband, who she feels she should obey.
(D) He wanted to return to his home, wife, and son.
This is an infinitive phrase.
It’s D it makes the most sense
The prevalent tone that this sentence conveys is sadness. The verb 'plodded' suggests exhaustion, 'dragging' implies hopelessness and 'empty night' could be a metaphor for their current perspective of their souls.
