Hello. You forgot to say that this question is about the poem "O Captain! My Captain!" by Walt Whitman.
In addition, you forgot to show what part A was referring to, so that it was possible to answer your question about art B.
Part A asks what the word "exulting" means in the third line of the poem. That word means that the population in the port was showing happiness and emotion.
Answer:
D "For you bouquets and ribbon'd wreaths - for you the shores a-crowding"
Explanation:
The poem is about a sailor's sadness about the captain's death, after a very difficult trip. The captain was an admirable leader and that is why the sailor regrets his death even in the face of the commemoration of the population for the ship having managed to reach the port.
In the third line of the poem, we can see that the population is "exulting" which means that they are happy and thrilled with the arrival of the ship and this happiness makes these people fill the beach and offer bouquets and ribbon'd wreaths for the captain.
