C) A - r, B - p, C - s, D - q
D) A - r, B - s, C - p, D - q
Correct Answer: D
Solution :
Starch, a polymer of glucose is the major reserve food (storage product) in plants. Haemoglobin is a transport protein found in blood which transported \[{{O}_{2}}\]and \[C{{O}_{2}}.\] RNA is formed from DNA through transcription and is used for protein synthesis during translation.
