Introduction:

Hormones are the chemical messengers that are synthesized and released by the endocrine glands. They play an important role in growth, development, and maintenance of life of a living organism.

Explanation of Solution

Hormones travel via the bloodstream to act on the specific target cell or tissue to carry out their function. The target cells possess the receptors that are specific for a particular hormone. Peptide hormone receptors are found on the plasma membrane, while the receptors specific for the lipid-soluble hormones are generally found inside the cytoplasm or the nucleus. Thus, the various cellular activities of the target cells are regulated by the hormones.

Conclusion

Therefore, it can be concluded that the term target cells can be correctly matched with option (c) regulated by hormones.
