What are the major factors affecting biodiversity today

Option (a) is the correct answer.

Explanation:

Physical activity is an activity in which work is done by our body. When we take rest, then our body feels refreshed and as a result, the efficiency to do more work is achieved by our body.

Hence, it is required to take some rest while training or workouts etc to regain the strength and avoid any kind of injury.

Whereas when we take little rest then our body feels exhausted. As a result, we should take adequate rest in order to work properly.

Thus, we can conclude that the statement you should rest as little as possible because it interferes with training is NOT true about rest and physical activity.
