Single correct option

Consider the following statements:
1. Insulin helps in lowering the level of glucose in the blood.
2. Deficiency of insulin causes goitre.
Which of the statements given above is/are correct?
  1. A. 1 only
  2. B. 2 only
  3. C. Both 1 and 2
  4. D. Neither 1 nor 2
Show answer and solution

Answer: (A) 1 only

Insulin lowers blood glucose, so statement 1 is correct. Deficiency of insulin results in diabetes mellitus, not goitre. Goitre, the swelling of the neck, is caused by a lack of iodine, which is needed to make thyroxine. Iodised salt is used to prevent it. So the hormone and the disease named in the two statements are linked to different glands and different deficiencies.
