Fill in the blank with a suitable preposition from the following options :

Mathura is famous __________ its temples. 

for

The correct answer is Option 3 - FOR

The correct preposition to fill in the blank is for. Mathura is famous for its temples.

The preposition "for" is used to indicate that something is known or regarded for a particular quality or characteristic. In this case, Mathura is known for its many temples. The other options, "with," "by," and "among," do not convey the same meaning of being known or regarded for something.
