Question Statement:
Read the passage:
'Photosynthetic efficiency in C3 crops like rice and wheat is inherently constrained by photorespiration catalyzed by the enzyme RuBisCO in the presence of oxygen. Engineering C4-like biochemical carbon concentrating mechanisms into C3 staples represents a promising frontier to enhance grain yield by over 30% under elevated atmospheric temperatures.'
What can be logically deduced from the passage?
Options:
- (A) RuBisCO enzyme operates with zero oxygenase activity in C3 plants
- (B) Photorespiration lowers the net photosynthetic yield in C3 crops
- (C) C3 crops have higher thermal tolerance than C4 crops naturally
- (D) Elevated atmospheric temperatures eliminate the need for RuBisCO
