Explanation:
Lysosomes are the membrane-bound organelles of the cell which plays an important role in cell repair mechanisms and digestion of biomolecules and foreign bodies. They contain hydrolytic enzymes which maintain digests a variety of the molecules and also maintain the acidic condition of the lysosomes.
Lysosomes also help in the immune response of the body as they digest the foreign bodies engulfed by the cell-like micro-organisms.
Since the phagocytosis process by white blood cells engulfs the microorganisms which gest digested by the lysosomes in a cell, therefore, is the best cell to study the lysosomes.
Thus, Option-C is the correct answer.
The answer is option D "test the effect of cyanide on algae." Ecologist are researchers who study how organisms interact with their environment so in this case they are testing how algae reacts to cyanide.

It wouldn't be option A, B, and C because you have to remember the job of a ecologist and the options are not jobs of one.
Hope this helps.
