Correct Option (c):
The correct matching of hormones with their associated items is as follows:
- A. Adrenaline: This hormone is secreted by the adrenal glands in response to stress, preparing the body for a 'fight-or-flight' response in situations involving anger, fear, or danger. Thus, A matches with 1.
- B. Estrogen: This is a primary female sex hormone responsible for the development and regulation of the female reproductive system and secondary sexual characteristics. Thus, B matches with 3.
- C. Insulin: Produced by the pancreas, insulin is crucial for regulating blood glucose levels by facilitating the uptake of glucose into cells. Thus, C matches with 4.
- D. Pheromones: These are chemical signals released by an organism that influence the behavior or physiology of other members of the same species, often playing a role in attracting partners through the sense of smell. Thus, D matches with 2.
Based on these matches, the correct code is 1342.
Incorrect Options:
Options (a), (b), and (d) present incorrect pairings. For example, option (a) incorrectly associates Adrenaline with 'Females' and Estrogen with 'Anger, fear, danger'. Similarly, other incorrect options fail to align the hormones with their accurate physiological functions or associated conditions.
