Here is a detailed explanation for the matching of hormones in List I with items in List II:

I. Adrenaline - (A) Anger, fear, danger: Adrenaline, also known as epinephrine, is a hormone released by the adrenal glands in response to stress or danger. It prepares the body for a fight-or-flight response, increasing heart rate, blood pressure, and energy levels. The release of adrenaline is commonly associated with emotions like anger, fear, and the perception of danger.

II. Estrogen - (C) Females: Estrogen is a group of hormones that are primarily responsible for the development and regulation of the female reproductive system and secondary sexual characteristics. It plays a crucial role in the menstrual cycle, pregnancy, and maintaining bone density. Estrogen levels are significantly higher in females compared to males.

III. Insulin - (D) Glucose: Insulin is a hormone produced by the pancreas that regulates blood sugar levels. It facilitates the absorption of glucose from the bloodstream into cells, where it is used for energy production or stored for future use. Insulin helps to lower blood sugar levels by promoting the uptake of glucose into cells.

IV. Pheromones - (B) Attracting partners through sense of smell: Pheromones are chemical substances produced and released by animals, including humans, to communicate and trigger responses in other individuals of the same species. They play a role in various social and reproductive behaviors, including attracting potential partners through the sense of smell. Pheromones can influence attraction, mating behavior, and social interactions.

Therefore, based on the functions and associations of these hormones, the correct matching is: I-A, II-C, III-D, IV-B.
