Answer:
D. Fixed percentage of RM method
Step-by-step explanation:
When we measure muscular endurance it is very important to make it equal to all participants. This can be done using a fixed percentage of a one-repetition maximum or 1RM. We can set it to 70% so a person who can lift 100kg would have to lift 70kg for as many repetitions that they can. This way a large and small person would be equal in weight but not in endurance.
