Answer:
B & D (see below)
Explanation:
The options for answers were:
a) We are faced with choices between good and bad.
b) It is necessary to make choices in life.
c) Choices are not mandatory.
d) Choices shape a person's life.
The poem is about reaching a point where a road branches and there are two options, equally appealing. So, not "good and bad", but a choice still has to be made. That's why B is correct, and A is wrong.
Obviously, where the road branches, a choice has to be made, so a choice is in fact mandatory- which means C is incorrect.
The rest of the poem talks about what the selection of that choice in road has resulted in, which is why D is also correct.
