You are right @Arun.

The Microstructure is the very small scale structure of a material, defined as the structure of a prepared surface of the material as revealed by a microscope above 25° magnification.

So microscope is the correct answer which was not present in above options (optical microscope is the wrong answer).

Nanostructure - optical microscope.

Reference Wikipedia (search for MICROSTRUCTURES).
