Troponin is a protein which is found on actin filament and myosin protein is found in myosin filament. Both actin and myosin are complex proteins in striated muscles.
Thymosin is a hormone secreted by the thymus that stimulates development of T cells. Prolactin is a hormone released by the pituitary gland that stimulates breast development and milk production in women. Rhodopsin, also known as visual purple, is not a hormone. It is a biological pigment in photoreceptor cells of the retina that is responsible for the first events in the perception of light

Correct categorization of chemical substances
Explanation:
Chemical substances can be categorized based on their chemical properties, functions, and structures. The correct categorization of chemical substances is important in understanding their roles in biological systems. The given options are:
a) Calcitonin and thymosin - Thyroid hormones: This is incorrect categorization because calcitonin and thymosin are not thyroid hormones. Calcitonin is a hormone secreted by the thyroid gland that regulates calcium levels in the blood, while thymosin is a hormone secreted by the thymus gland that stimulates the production of T cells.
b) Pepsin and prolactin - Two digestive enzymes secreted in stomach: This is incorrect categorization because pepsin is a digestive enzyme secreted in the stomach, while prolactin is a hormone secreted by the pituitary gland that stimulates milk production in mammary glands.
c) Troponin and myosin - Complex proteins in striated muscles: This is the correct categorization because troponin and myosin are complex proteins found in striated muscles. Troponin is a regulatory protein that controls muscle contraction, while myosin is a motor protein that generates force during muscle contraction.
d) Secretin and rhodopsin - Polypeptide hormones: This is incorrect categorization because secretin is a polypeptide hormone secreted by the small intestine that stimulates the pancreas to secrete bicarbonate to neutralize stomach acid, while rhodopsin is a protein found in the retina of the eye that is involved in vision.
Therefore, the correct categorization of chemical substances is troponin and myosin - complex proteins in striated muscles.
