Given below are two statements:
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
| 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
