From the question you can immediately infer that it's either B or D, as A and C basically mean the same thing and it isn't anything related to a microscope. I can tell you now that you don't need an electron microscope to see cells, they're only required for the atomic level.
Therefore, the answer is B, as you can't see cells without a microscope but you only need a light microscope, not an electron microscope.

Answer:
c. time to reach maximum tension
Explanation:
Muscle tension is defined as the contraction of muscles for an extended period of time. Physiological effects such as running and exercise of stress are the cause of muscle tension.
Skeletal muscle fibres into two types including slow-twitch (type I) and fast-twitch (type II).
- Muscle fibres of type I are more effective over long time periods. They are used mainly for postural maintenance (such as keeping the head upright), or mobility exercises (running).
- Type II muscle fibres use anaerobic breathing, and are stronger than Type I fibres for quick bursts of energy, even though they fatigue quicker.
So the muscle fibers divided on the basis of time to reach maximum tension while doing physiological activities.
Hence, the correct option is C.
