Answer 1

Thanks for asking the question.
Well, option (a) is the correct one, which states:
1. Ocean as a carbon sink will be adversely affected.
2. Food chains in the ocean will also be affected.
Phytoplankton is a base of food chain. It it ends it will take a few months for the chain of starvation to start the entire way up to animals like shark, and it will happen very fast.
Hope it helps.
