Given below are two statements:
In the light of the above statements, choose the correct answer from the option given below:
| Statement I: | In \(\text{C}_3\) plants, some \( \text{O}_2\) binds to \(\text{RuBisCO},\) hence \(\text{CO}_2\) fixation is decreased. |
| Statement II: | In \( \text{C}_4\) plants, mesophyll cells show very little photorespiration while bundle sheath cells do not show photorespiration. |
In the light of the above statements, choose the correct answer from the option given below:
| 1. | Both Statement I and Statement II are False |
| 2. | Statement I is True but Statement II is False |
| 3. | Statement I is False but Statement II is True |
| 4. | Both Statement I and Statement II are True |
