Answer»

The SENTENCE uses the FORM may leads to, which is incorrect and needs improvement.

The correct form MUST be with the modal verb 'may'+ the simple present TENSE form 'lead' to.

The form 'might be LEADING' can also be correct here.

The only alternatives that improve the sentence are B and C.

None of the other alternatives can make the sentence meaningful.

Therefore, the correct answer is option 3.
