Question

I. Walk carefully lest you.... stumble.
(A) would
(B) should
(C) could
(D) must​

Answer 1

Answer:

Answer

Correct option isC

should

Option C is the correct answer because 'lest' has a negative meaning. Therefore, it should not be used with not. The only auxiliary verb that can follow lest is should.

For example -Work hard lest you should fail. OR Work hard lest you fail. (NOT Work hard lest you should not fail.)

Option A and D are incorrect because they are implied in the past tense whereas the statement is in the present tense.

Option B is incorrect because 'must' is used to express necessity, but here the condition for failing is being careless, and hence not a necessary thing to happen.
