Correct Answer:
(B) Decreases
Explanation:
This is a somewhat tricky question. While resistance training might cause mitochondria to increase in number or remain the same, the density of the mitochondria is related to the amount of mitochondria relative to muscle area. The set and rep range used here indicate that the resistance training is geared towards muscle hypertrophy. If the working muscles increase in size, then the mitochondrial density decreases.
