The answer to the given question is option “B”. The poem “Richard
Cory” cannot be a sonnet as a sonnet always has 14 lines. So the chance of
option “d” being the answer is not at all possible. There are no blank verses
in the poem “Richard Cory” and so there is also no chance of option “C” being
the answer to the given question. There is also no lack of rhyme scheme and so
option “A” cannot be the answer. The poem does have a surprise ending as
Richard Cory shoots himself in the head after reaching home. So the correct
answer is option “B”.
