Match the hormones in List I with items in List II and select the correct answer using the codes given below the Lists

List I | List II
I. Adrenaline | (A) Anger, fear, danger
II. Estrogen | (B) Attracting partners through sense of smell
III. Insulin | (C) Females
IV. Pheromones | (D) Glucose

The correct answer is Option 3 (I-A, II-C, III-D, IV-B). This matching correctly identifies the physiological functions and origins of the listed biochemical substances:

• I - Adrenaline (A): Known as the "fight or flight" hormone, it is secreted by the adrenal glands in response to emotional stress like anger, fear, or danger.
• II - Estrogen (C): This is the primary sex hormone responsible for the development and regulation of the female reproductive system and secondary sexual characteristics.
• III - Insulin (D): Secreted by the pancreas, its primary role is to regulate blood glucose levels by facilitating its uptake into cells.
• IV - Pheromones (B): These are chemical signals released by organisms to communicate with others of the same species, often used for attracting partners through the sense of smell.

Options 1, 2, and 4 are incorrect as they mismatch these well-established biological functions, such as incorrectly linking Insulin to smell or Estrogen to danger.
