How do steroid hormones differ from amino acid-derived hormones in terms of solubility and receptor interactions?

• A. Steroid hormones are water-soluble and bind membrane receptors, while amino acid-derived hormones are lipid-soluble and bind intracellular receptors.
• B. Both steroid and amino acid-derived hormones are water-soluble and bind membrane receptors.
• C. Steroid hormones are lipid-soluble and diffuse through membranes to bind intracellular receptors, while amino acid-derived hormones are water-soluble and bind membrane receptors.
• D. Both steroid and amino acid-derived hormones are lipid-soluble and bind intracellular receptors.
