Correct Option The correct option is (c). Explanation Deficiency diseases are pathological conditions caused by the lack of specific essential nutrients, such as vitamins and minerals, in the diet over a prolonged period. Statement-wise Analysis - Statement 1 is Correct: Beriberi is caused by a deficiency of Vitamin B1 (Thiamine). Its symptoms typically include weak muscles and severe fatigue. - Statement 2 is Incorrect: Rickets is caused by a deficiency of Vitamin D. It results in the softening and bending of bones, not hardening. The condition leads to skeletal deformities such as bowed legs. - Statement 3 is Correct: Goiter is caused by a deficiency of Iodine. It is characterized by the enlargement of the thyroid gland, which manifests as a visible swelling in the neck region. Key Takeaway Rickets involves the softening of bones due to Vitamin D deficiency, whereas Beriberi is caused by Vitamin B1 deficiency, and Goiter involves thyroid enlargement due to Iodine deficiency.
