The Correct Option is B
Approach Solution - 1
Steroid hormones are secreted by cells of adrenal cortex and endocrine cells of gonads. All steroid hormones are lipid derived from cholesterol. Many enzymes are involved in the biosynthetic pathway of steroid hormonessome of which are located in SER membrane and some occur in mitochondria. Protein hormones are secreted by parathyroid, pituitary glands, secretory cells of hypothalamus and pancreas. These are small peptides of 3-200 amino acid monomers. Amino Acid Derivative (AAD) hormones are smallest hormones and derived from tyrosine, histidene and tryptophan.

Approach Solution -2
Natural steroid hormones are often produced from cholesterol found in the gonads and adrenal glands. They are lipids in nature, and because they are fat-soluble, they pass through the cell membrane. Then, depending on the steroid hormone, they attach to steroid hormone receptors (which might be nuclear or cytoplasmic). This causes changes within the cell. Steroid hormones are often transported through the bloodstream by attaching to certain carrier proteins, such as sex hormone-binding globulin or corticosteroid-binding globulin.

Concepts Used:
Nucleic acids
Nucleic acids are explained as long-chain polymeric molecules, where the monomer (the repeating unit) is referred to as the nucleotides. Thus many times nucleic acids are referred to as polynucleotides. The two main kinds of nucleic acids are-
Deoxyribonucleic Acid (DNA)
Chemically, DNA is a composition of a pentose sugar, phosphoric acid, and some cyclic bases that have nitrogen in them. DNA has β-D-2-deoxyribose in it, in the form of the sugar moiety.
Ribonucleic Acid (RNA)
The RNA molecule is a composition of phosphoric acid, a pentose sugar, and some cyclic bases containing nitrogen. The sugar moiety inside RNA molecules is β-D-ribose.
