a. del gas
b. de los neumáticos
c. del parabrisas
d. de los frenos
select the best answer from the choices provided
a. del gas
b. de los neumáticos
c. del parabrisas
d. de los frenos

I would contend that the right answer is actually the B) "de los neumáticos."  

Explanation: Just to elaborate a little on the answer, it can be added that the only object from the list that has pressure (presión) in it is the tire (neumático). Gas (option A), windshield (option C), and breaks (option D) do not have pressure in them. Therefore, it is correct to say that the employee working at the gas station did not check the tire pressure.
