Answer 1

Hint: It is an observation that most of the yellow, orange, and red vegetables and fruits are rich in Vitamin A.Vitamin A is also known as retinol. The precursor of retinol is present in vegetables and fruits which is known as carotenoids.

Complete answer:
Carrot contains 16,706 IU of Vitamin A per 100gm. Carrot is orange in colour so it is rich in Vitamin A.
Mango contains 1082 IU of Vitamin A per 100 gm. Mango is yellow and has carotenoids.
Apple has 54 IU of Vitamin A per 100gms. It is known for its fibre and Vitamin C content, but it is red/yellow /green in colour, which means it is having carotenoids.
Yeast is a microorganism which converts carbohydrate into alcohol and carbon-di-oxide. Yeast is eukaryotic in nature. It has a high content of Vitamin B-complex and amino acid.

Hence, the correct answer is option (A).
