B
Correct answer
Explanation
Carbohydrates are used by body mainly as a source of energy.
Carbohydrates represent the most important source of energy for the body, and are vital for a varied and balanced diet.
The building blocks of all carbohydrates are sugars and they can be classified according to how many sugar units are combined in one molecule. Various forms of sugar, such as glucose and sucrose (table sugar), are simple carbohydrates.
They are small molecules, so they can be broken down and absorbed by the body quickly and are the quickest source of energy. They quickly increase the level of blood glucose (blood sugar).

A
Correct answer
Explanation
Aflatoxins are naturally occurring mycotoxins that are produced by Aspergillus flavus and Aspergillus parasiticus, species of fungi. Aflatoxins are toxic and among the most carcinogenic substances known. After entering the body, aflatoxins may be metabolized by the liver or hydroxylated to become the less harmful aflatoxin M1. Grains such as corn, wheat, and rice, as well as nuts and legumes, are often contaminated with molds, often as a result of poor growing conditions, substandard or extended storage. Molds called aflatoxins can easily grow and produce a very potent carcinogen.
