ANSWER
The correct answers are option B and D.

EXPLANATION
The given expression is

We need to simplify the above expression in order to determine the option that is equivalent to it.
The least common denominator for the last two fractions is 3.
This implies that,

We simplify to obtain,

This further simplifies to give us,

This is option B.
When we further factor -4, we get,

Note first that several months have 30 days (each): April, June and September.
(A) could not be correct, since the month in question could have 28, 29 or 31 days.
(B) See (A), above. If the month in question does not have 30 days, then the month could NOT be April, June or September. Reject (B).
