Show Worked Solution

B is correct: Heavy, low-repetition training causes muscle fibres to increase in size.

Other Options:

A is incorrect: This would cause muscle growth, not muscle wasting.
C is incorrect: High repetitions develop endurance, not heavy low reps.
D is incorrect: Heavy training develops fast-twitch fibres, not slow-twitch.
