<h3>What is a Microscope?</h3>

A microscope may be defined as a type of laboratory instrument that is significantly utilized to examine or observe objects that are too small to be visualized by the unaided eye.

Dissecting microscopes possess a lower magnification power as compared to compound light microscopes. Due to this, dissecting microscopes are used to visualize larger objects like tissues. Compound light microscopes use more than one glass lens. These types of microscopes are used to examine living cells.

Therefore, a compound light microscope has higher magnification is a statement that describes the utilization of a compound light microscope is better to view the structures of these organisms than a dissecting microscope. Thus, the correct option for this question is C.
