61Both are correct.
If a graph is plotted of the rate of photosynthesis vs sunlight intensity, it increases until about 10% of full sunlght, after which it becomes constant. This is called light saturation.
Plants convert only about 1-4% of the light they absorb into chemical energy, which was what was asked in Chakravyuh.
These two are different things.
