I think the answer should be E for this question.

From 1, we dont know anything about other months. Hence, not sufficient.

From 2, To calculate the occupancy rate for February, we need to know the occupancy rate on 31st January, but we dont know the occupancy rate on 31st January. Hence not sufficient.

From 1 and 2, we still dont know the occupancy rate on 31st January. Hence not sufficient.

Answer E.
