Answer #1

The building block of carbohydrates is sugar. Hence option (a) is correct.

Explanation :- This is because, in option (b) Alpha amino acid is a building block of protein. And in option (c), fatty acid is a building block of lipids. And in option (d), DNA is the example of nucleic acids & the building block of nucleic acid is nucleotides.

Generally carbohydrates are sugars or a long chain of sugars.the examples of carbohydrates are given below :- glucose, starch, glycogen & cellulose.

Importance of carbohydrates in our life :- we get our energy to do work ( in our daily life) from carbohydrates rich sources like fruits, vegetables & grains.
