Select the INCORRECT statement with regards to vitamins.

Correct option is C

The correct answer is (c) Some bacteria in the gut do not produce vitamins.
Let's analyze each option to identify the incorrect statement:
(a) Plants can synthesise almost all vitamins: This statement is correct. Plants can indeed synthesize most of the vitamins that are essential for their own metabolism and for humans when we consume plant-based foods.
(b) Vitamins are organic compounds: This statement is also correct. Vitamins are classified as organic compounds because they contain carbon and are essential for various metabolic functions.
(c) Some bacteria in the gut do not produce vitamins: This statement is incorrect. In fact, certain bacteria in the gut are known to produce vitamins, particularly B vitamins (such as B12) and vitamin K. These bacteria play a crucial role in supplementing our body's vitamin requirements.
(d) Most of the vitamins cannot get synthesised in sufficient amount in our body: This is correct. Humans cannot synthesize most vitamins (e.g., vitamin C, several B vitamins) in sufficient quantities, which is why they must be obtained from the diet.
Information Booster:
· The human gut microbiota is known to produce several vitamins, including vitamin K and some B-complex vitamins, contributing to their absorption and utilization in the body.
· Vitamins are essential organic compounds required in small quantities for various biochemical and physiological functions, but they cannot be synthesized adequately by the human body.
· Plants are generally capable of producing vitamins like vitamin C and beta-carotene (a precursor of vitamin A), which are beneficial for humans when consumed.
