Fill in the blank with an appropriate Article : Mr. Anand became ____…

The correct answer is Option (1) - the

The correct answer is “the”.

 Mr. Anand became the Principal of the college in 1995.

Reason:
We use “the” before a singular noun when referring to a specific position or title held by a particular person. Here, “Principal of the college” refers to a definite, unique position — there is only one principal in that college.

So the complete sentence is:
Mr. Anand became the Principal of the college in 1995.
