Question

You ___11___ also have a check-up at least once a year during service.

• A. should
• B. would
• C. could
• D. need

Answer 1

The correct option is A should

Option A is correct because 'should' is used to make offers and suggestions, and to ask for advice, here in the above statement an advice is being made to have a check up at least once a year.

Option B and C are incorrect because could and would are used in the form of past tense.

Option D is incorrect because 'need' is used when it is a necessity and not an advice or suggestion, which is not true in this case.

need is always followed by 'to'.
