RRB NTPC 2025 Under Graduate CBT 1 Question Paper PDF (20-Jun-2026) (Shift 3)
The correct answer is

Thiamin

The vitamin B complex is a group of water-soluble vitamins. Thiamin is vitamin B1, one of the members of this group, and it helps the body convert carbohydrates into energy.

The other options are fat-soluble vitamins: Tocopherol is vitamin E, Calciferol is vitamin D and Retinol is vitamin A, so none of them belongs to the water-soluble B complex.

Hence, the vitamin included in the vitamin B complex is Thiamin.
