Answer: D: None 
Explanation: Peptide hormones are proteins that have endocrine functions in living animals.A steroid hormone is a steroid that acts as a hormone. Steroid hormones can be grouped into 2 classes, coicosteroids (typically made in the adrenal coex, hence coico-) and sex steroids (typically made in the gonads or placenta). Within those 2 classes are 5 types according to the receptors to which they bind: glucocoicoids and mineralocoicoids (coicosteroids) and androgens, estrogens, and progestogens (sex steroids). Vitamin D derivatives are a sixth closely related hormone system with homologous receptors. They have some of the characteristics of true steroids as receptor ligands.Ref: Ganong&;s review of medical physiology; 24th edition; page no: 302
