Arrange the following events in the correct sequence.
1) Thyroid gland secretes less hormone
2) Homeostasis
3) High concentration of thyroid hormones
4) Anterior pituitary secretes less TSH

A) 2 → 1 → 4 → 3
B) 2 → 3 → 4 → 1
C) 3 → 4 → 1 → 2
D) 4 → 3 → 1 → 2
E) 1 → 4 → 3 → 2

Thyroid Gland

An endocrine gland that lies anterior to the trachea and releases hormones that regulate the rate of metabolism.

TSH

Thyroid-stimulating hormone, a pituitary hormone that stimulates the thyroid gland to produce thyroid hormones.

Homeostasis

The regulation of internal conditions within the cells or organisms to maintain stable, constant conditions necessary for survival.

Final Answer :
C
Explanation :
The correct sequence starts with a high concentration of thyroid hormones (3), which leads to the anterior pituitary secreting less TSH (4). This reduction in TSH causes the thyroid gland to secrete less hormone (1), eventually leading to the restoration of homeostasis (2).
