Show Hint
To easily solve biological process questions, remember the complementary nature of photosynthesis and respiration.
Photosynthesis: Energy storage (endergonic), occurs in chloroplasts, synthesis of sugars.
Respiration: Energy release (exergonic), occurs in cytoplasm and mitochondria, breakdown of sugars.

The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Photosynthesis is an anabolic, endergonic biological process through which green plants, algae, and certain bacteria convert light energy into chemical energy stored in the covalent bonds of organic molecules (sugars).
Step 2: Detailed Explanation:
Let us analyze each statement individually:
Statement (A): "Produces sugars from energy" is correct.
Photosynthesis utilizes radiant energy from sunlight to drive the synthesis of glucose (sugar) from carbon dioxide and water:
\[ 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \]
Statement (B): "Occurs in most cells" is incorrect.
Photosynthesis does not occur in most plant cells (for example, root cells, epidermal cells, and deep woody tissue cells do not photosynthesize). It is localized to specialized green tissues.
Statement (C): "Occurs only in cells with chloroplasts" is correct for eukaryotic plants.
Chloroplasts contain chlorophyll pigments, thylakoid membranes, and enzymes necessary to capture light energy and run the Calvin-Benson cycle.
Statement (D): "Energy is released" is incorrect.
Photosynthesis is an energy-storing process (endergonic).
Energy release occurs during cellular respiration, which breaks down sugars to produce ATP.
Evaluating the choices, only (A) and (C) are correct.
Step 3: Final Answer:
The correct combination is (A) and (C) only.
