A sentence has been given with a blank to be filled with an appropriate word. Choose the correct alternative.
Either he or I ______ leading the team tomorrow.

Correct option is C

The correct option to fill in the blank is (c) am.
Explanation:
When two subjects are joined by “ either…or”, the verb agrees with the subject closer to it.
Here, “I” is closer to the blank, so we use “ am”, the correct helping verb for "I".
Correct sentence: Either he or I am leading the team tomorrow.
Grammatical Rule Used:
Subject-verb agreement with correlative conjunctions:
· With "either...or" / "neither...nor", the verb agrees with the nearest subject.
Example:
· Either you or she is attending.
· Either you or I am responsible.
