Which of the following statements about steroid hormones is true? A. They bind with receptor proteins in the plasma membrane.
B. They bind to carrier proteins in order to be transported in the blood to
their target cells.
C. They are synthesized from epinephrine in the adrenal gland.
D. They are mostly derivatives of the amino acid tyrosine.

B. They bind to carrier proteins in order to be transported in the blood to

their target cells.

Explanation:

Steroid hormones are belongs to the class of chemical compound called steroid. Steroid hormones are majorly secreted by three glands - ovaries, testes and adrenal cortex.

Steroid hormones are released in the blood and are allowed to bind to the specific carrier proteins such as corticosteroid-binding globulin and albumin which helps them to carry to the target cells for the functioning.

The steroid hormone binds to receptor proteins in the target cell and not in the plasma membrane

Hence, the correct answer is "B. They bind to carrier proteins in order to be transported in the blood to  their target cells."
