Why is balance between work pace and body capacity important in ergonomics?

Correct answer: To prevent excessive fatigue and errors

The direct answer is A: to prevent excessive fatigue and errors. Human bodies have limits. If work is demanded faster than a person can safely manage, breathing, muscles and attention become strained. As fatigue rises, concentration falls and mistakes become more likely. A suitable pace allows short recovery, steady attention and safer quality. Option A is correct because it states the real ergonomic purpose of matching pace with capacity. Option B is wrong because ergonomics does not try to make work impossible. Option C is wrong because comfort and recovery are important, not things to remove. Option D is wrong because communication helps coordination and safety. The fact chain is: suitable pace + human capacity → less fatigue → fewer errors. Remember that ergonomics balances productivity with health, safety and accuracy.
