Answer 2

Answer:

Assertion (A): Human RBC lack nucleus.

Reason (R): RBCs perform the function of transportation of food materials.​

Here, the Assertion is True and the Reason is True and also the Reason is the correct explanation of Assertion

This is because,

it is true that RBC lacks nucleus and cell organelles, this is because there is a red pigment called haemoglobin in RBC which allows them to transport oxygen. Inorder to carry the maximum amount of haemoglobin and oxygen they lack nucleus. So the reason why they lack nucleus is because they want to carry maximum amount of oxygen and food (mainly protien).

Hope this was clear and useful

Hopefully you learned the concept too!!
