Answer:

The correct answer is option E. only water-soluble hormones use second messengers.

Explanation:

Water soluble hormones can not diffuse through cell membranes as only lipid soluble molecules can pass through the cell membranes and these hormons are not lipid soluble molecules,

These water hormones are usually glycoproteins, peptide and catecholamnies such as TSH, FSH, LH and insulin. these hormones need second messengers because there receptors are present on the plasma membrane.

Thus, the correct answer is option - e.  only water-soluble hormones use second messengers.
