The minimum capacity, in BTU/h, of an air conditioning unit for environments without sun exposure, can be determined as follows:
  • $600 \mathrm{BTU}/\mathrm{h}$ per $\mathrm{m}^{2}$, considering up to two people in the environment;
  • for each additional person in this environment, add 600 BTU/h;
  • add another 600 BTU/h for each electrical appliance in operation in the environment.

An air conditioning unit will be installed in a room, without sun exposure, with dimensions $4\mathrm{~m} \times 5\mathrm{~m}$, in which four people remain and which has a television set in operation.
The minimum capacity, in BTU/h, of this air conditioning unit should be
(A) 12000.
(B) 12600.
(C) 13200.
(D) 13800.
(E) 15000.
