Answer:
The correct answer is 4.
Step-by-step explanation:
The four times are indicated by the 4 above the other 4, the numerator, the denominator; on the bottom four, it indicates that in each of the parts a note with the value of a black one enters. Thus, 4 blacks would enter the whole measure. That said, as a final note, remember that each 4/4 measure has four pulses, the first and the third pulse is strong and the second and fourth are weak.
