keywords: 

{'iodine deficiency': [0, 0, 1, 0], 'iodine': [2, 1, 1, 1], 'thyroid gland': [1, 0, 0, 2], 'adrenaline': [1, 0, 0, 0], 'goiter': [0, 0, 2, 0]}

The correct answer is option 4 - "2 only".

Let`s analyze each statement:

1. Iodine is necessary for the thyroid gland to make adrenaline.

This statement is incorrect. Iodine is actually used by the thyroid gland to produce thyroid hormones, not adrenaline. Adrenaline is produced by the adrenal glands.

2. Iodine deficiency leads to goiter in human beings.

This statement is correct. Goiter is a condition characterized by the enlargement of the thyroid gland. Iodine deficiency is one of the main causes of goiter.

3. Iodine is secreted by the pancreas and helps in regulating cholesterol level.

This statement is incorrect. Iodine is not secreted by the pancreas. It is primarily utilized by the thyroid gland for the production of thyroid hormones, which play a role in regulating metabolism and growth.

Therefore, only statement 2 is correct, and the correct answer is option 4.
