C Correct answer
Explanation

This option is correct because chemotaxis is the phenomenon in which somatic cells, bacteria and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment.  In multicellular organisms, chemotaxis is critical to early development (e.g. movement of sperm towards the egg during fertilization) and subsequent phases of development (e.g. migration of neurons or lymphocytes) as well as in normal function.
