Answer: Option A.
The two types of chlorophyll are chlorophyll A and B.
Explanation:
Chlorophyll is the green pigments present in chloroplast (organelles) that is found in plants which is used for photosynthesis by reacting with carbon dioxide and water to produce carbohydrates. The two types of chlorophyll are; chlorophyii A and chlorophyll B.
Chlorophyll A is the primary photosynthetic pigment that absorb energy from blue- violet light and orange red lights wavelengths.
Chlorophyll B is the accessory pigment to receive energy and transmit it to chlorophyll A. Chlorophyll B absorbs energy from green lights wavelengths.

In the field of histopathology, the tissues to be observed under the microscope are cut in very thin slices. The thin slices make the tissue transparent, and thus, it becomes easier to observe the internal structures and accurately diagnose a disease. The tissues slices cut for the observation are generally not more than 3 micro meters in their thickness.
Hence, the answer is 'to make the tissues transparent and easier to observe'.
