Which one of the following hormone is a steroid?

Hormones are classified into structural groups including peptides and steroids. Cortisone is a steroid hormone belonging to the glucocorticoid class, which are synthesized from cholesterol in the adrenal cortex [t1][t2]. Steroid hormones are lipophilic and typically end in the suffixes '-one' or '-ol' [t5][t7]. In contrast, insulin and glucagon are peptide hormones produced by the pancreas to regulate blood sugar levels [c2][t5][t6]. Oxytocin is a nonapeptide (peptide hormone) produced in the hypothalamus and released by the posterior pituitary [t1][t4]. While insulin and oxytocin follow the common 'in' suffix naming convention for peptides, glucagon is also a peptide despite its different suffix [t7]. Therefore, among the given options, only cortisone (a glucocorticoid) fits the structural classification of a steroid hormone [t2][t3].
