Final Answer :
B
Explanation :
The training regimen of a competitive weightlifter primarily aims to increase the average number of myofibrils per muscle fiber, which contributes to muscle hypertrophy and strength gains. This process is known as muscular hypertrophy, a key goal in weightlifting training.
