C4 photosynthetic efficiency is more than C3 pathway because:
- APhotorespiration is present in C3
- BPhotorespiration is present in both C3 and C4
- CPhotorespiration is fast in C4 plants
- DPhotorespiration is suppressed in C4 plants

Assertion (A): When $P_{c o_2}$ is high and $P_{o_2}$, is low as in the tissues, more binding of carbon dioxide occurs whereas, when the $P_{c o_2}$ is low and $P_{c o_2}$, is high as in the alveoli, dissociation of $CO _2$ from carbamino- hemoglobin takes place.
Reason (R): $P_{c o_2}$, is a major factor that could affect the binding of $CO _2$ with hemoglobin.
Reason (R): $P_{c o_2}$, is a major factor that could affect the binding of $CO _2$ with hemoglobin.
- ABoth A and R are true and R is the correct explanation of A
- BBoth A and R are true but R is not the correct explanation of A.
- CA is true but R is false.
- DA is false but R is true.
Assertion (A): Mushrooms are called fairy rings.
Reason (R): Mushroom consists of two parts-stipe and pileus.
Reason (R): Mushroom consists of two parts-stipe and pileus.
- ABoth A and R are true and R is the correct explanation of A
- BBoth A and R are true but R is not the correct explanation of A
- CA is true but R is false.
- DA is false but R is true.
Assertion (A): In certain industries, especially those involving grinding or stone-breaking, so much dust is produced, a long exposure can give rise to occupational respiratory disorders.
Reason (R): It produces inflammation leading to fibrosis and thus causing serious lung damage.
Reason (R): It produces inflammation leading to fibrosis and thus causing serious lung damage.
- ABoth A and R are true and R is the correct explanation of A.
- BBoth A and R are true but R is not the correct explanation of A
