Option 1 states that both statements are individually true and statement II is the correct explanation of statement I.

Statement I states that autotroph plants contain the pigment chlorophyll for meeting their requirement of carbon and energy. This can be considered true because autotrophs, such as plants, are able to produce their own food through the process of photosynthesis. Chlorophyll is the pigment found in plant cells that allows them to absorb sunlight and convert it into energy.

Statement II states that photosynthesis is the process of converting water into food using sunlight and oxygen. This statement is not an accurate explanation of statement I because it does not specifically mention the role of chlorophyll in photosynthesis or the requirement of carbon for the production of food.

Option 2 states that both statements are individually true but statement II is not the correct explanation of statement I. This option aligns with the correct answer because, as mentioned earlier, statement II does not provide an accurate explanation of statement I.

Option 3 states that statement I is true but statement II is false. This option aligns with the correct answer because statement I is true, but statement II is not an accurate explanation of statement I.

Option 4 states that statement I is false but statement II is true. This
