Q. Toxic agents present in food which interfere with thyroxine synthesis lead to the development of

A) Thyrotoxicosis
B) Toxic goitre
C) Cretinism
D) Simple goitre
Explanation

[Solution from source] Substances in food that block thyroid hormone synthesis (goitrogens) lower thyroxine levels. The pituitary responds by releasing more TSH, so the gland enlarges into a simple (non-toxic) goitre. Thyrotoxicosis and toxic goitre are conditions of excess thyroxine. Answer (4).
