Choose the correct labelling for the given figure.

The rate of photosynthesis does not depend on .........

The formation of chlorophyll in young plant seedlings is induced by .........

Identify the incorrect sentences:
$(I)$ Humidity in the atmosphere is relatively higher in areas where light becomes a limiting factor for plants.
$(II)$ An increase in light intensity beyond a certain point causes the breakdown of chlorophyll,leading to a decrease in the rate of photosynthesis.
$(III)$ $C_4$ plants respond to higher temperatures and show higher rates of photosynthesis,while $C_3$ plants have a much lower temperature optimum.
