The correct answer is option 'C': A: 1, B: 3, C: 4, D: 2.

Hormones play a crucial role in regulating various physiological processes in the human body. They are chemical messengers that are secreted by various glands and travel through the bloodstream to target cells or organs, where they exert their effects. Let's match the hormones in List-I with the corresponding items in List-II:

A. Adrenaline - 1. Anger, fear, danger
B. Oestrogen - 3. Females
C. Insulin - 4. Glucose
D. Pheromones - 2. Attracting partners of smell through sense

Now, let's discuss each match in detail:

A. Adrenaline - 1. Anger, fear, danger:
Adrenaline, also known as epinephrine, is a hormone released by the adrenal glands in response to stress or danger. It plays a crucial role in the body's fight-or-flight response. When a person experiences anger, fear, or perceives danger, the release of adrenaline prepares the body for action by increasing heart rate, dilating blood vessels, and increasing blood flow to muscles. This physiological response helps in dealing with the perceived threat.

B. Oestrogen - 3. Females:
Oestrogen is a group of hormones primarily produced by the ovaries in females. It plays a significant role in the development and regulation of the female reproductive system. Oestrogen is responsible for the development of secondary sexual characteristics in females, such as breast development, widening of hips, and the onset of menstruation. It also helps regulate the menstrual cycle and is involved in maintaining pregnancy.

C. Insulin - 4. Glucose:
Insulin is a hormone produced by the pancreas that regulates blood sugar levels. When we consume carbohydrates, they are broken down into glucose, which enters the bloodstream. Insulin is then released in response to high blood glucose levels. It acts by facilitating the uptake of glucose by cells, thereby lowering blood sugar levels. Insulin also promotes the storage of excess glucose in the liver and muscles as glycogen.

D. Pheromones - 2. Attracting partners of smell through sense:
Pheromones are chemical substances produced by organisms, including humans, that are released into the environment to communicate with others of the same species. In humans, pheromones are primarily involved in attracting potential partners through the sense of smell. They can influence attraction, sexual behavior, and mood. While the exact pheromones and their effects in humans are still being studied, they are believed to play a role in mate selection and social interactions.

In conclusion, the correct match for the hormones in List-I with the corresponding items in List-II is:

A: Adrenaline - 1. Anger, fear, danger
B: Oestrogen - 3. Females
C: Insulin - 4. Glucose
D: Pheromones - 2. Attracting partners of smell through sense
