Vitamin B12 (cyanocobalamin) is a complex vitamin that contains the trace mineral cobalt. Vitamin K is essential for the synthesis of prothrombin and other clotting factors in the liver. Beriberi is caused by a deficiency of Vitamin B1 (thiamine), whereas Vitamin C deficiency causes scurvy. Thus, statements 1 and 2 are correct.

Explanation:
The pituitary gland is a pea-sized endocrine gland located at the base of the brain, in a bony cavity called sella turcica, attached to the hypothalamus by a stalk (infundibulum). It is divided into anterior and posterior pituitary, secreting hormones that regulate growth, reproduction, metabolism, and other endocrine glands. Thus, it's in the head, not neck or abdomen.
