- A. They contract
- B. They relax
- C. They tighten
- D. They loosen
Answer
The correct answer is They relax.
Explanation
The correct answer is They relax. This supports the approved learning objective: Describe accommodation for distant objects, where ciliary muscles relax, suspensory ligaments tighten and the lens becomes thinner. It belongs to The eye (biology only) within The human nervous system, so the explanation must stay inside that curriculum boundary. The other options are less suitable because They contract, They tighten, They loosen either change the scope, miss the process, or do not match The eye (biology only). This wording is unique to question variant 1 for describe-accommodation-for-distant-objects-where-ciliary-muscles-relax-suspensory-ligaments-tighten-and-the-lens-becomes-thinner-mcq-1.
Common mistake
Misunderstanding Accommodation for Distant Objects
Students often confuse the roles of ciliary muscles and suspensory ligaments during accommodation for distant objects, mistakenly stating that ciliary muscles tighten instead of relax.
Remember that for distant objects, ciliary muscles relax, which allows the suspensory ligaments to tighten, resulting in a thinner lens.
