Question

Before joining you __10__ have a medical check up.

• A. can
• B. could
• C. must
• D. would

Answer 1

The correct option is C must

Option C is the correct answer because 'must'expresses compulsion or strong obligation which is correct here because getting a medical check up is compulsory.

Option A is incorrect because 'can' is used to express ability to do something or is used to give permission, which is not correct here because getting a medial check up is necessary and not a choice, and is definitely doable.

Option B and D are incorrect because they are in the past tense.
