In my opinion, the whole poem is quite ironic - although she is mentioning the exultation and the royal color of death, the poem itself begins with the narrator saying that she cannot breathe - that she doesn't want to die.
So, I would say that the ironic parts are:
Exultation is the going
Of an inland soul to sea, -
Past the houses, past the headlands,
<span>Into deep eternity!</span>
I believe A is the correct answer
Apollo is the god who darts around the world his rays
the thesis statement is the answer
People is the object because they are the recipient of the action.
They is the subject because they are the ones taking action.
