B-1 corresponds to which vitamin?

Explanation:
B-1 is the designation for thiamin, a water-soluble B vitamin. In the body, thiamin is converted to thiamin pyrophosphate, a key coenzyme for several enzymes involved in carbohydrate metabolism. It helps pyruvate dehydrogenase connect glycolysis to the TCA cycle and also supports α-ketoglutarate dehydrogenase and transketolase in the pentose phosphate pathway. This role makes thiamin essential for energy production and proper nervous system function. The other vitamins listed map to different B vitamins—riboflavin (B2), niacin (B3), and pantothenic acid (B5)—not to B-1.
