Which of the following are PRODUCTS of the light-dependent reactions in photosynthesis? A) Water
B) Oxygen
C) Carbon Dioxide
D) NADPH
E) Sugar

Oxygen, NADPH, and although it isn't a choice, ATP

Explanation:

The light-dependent reactions get their electrons by splitting water and taking one of its electrons. The splitting of water results in seperated oxygen and hydrogen. After this, the electron  gets excited by light energy and travels through PS2 and PS1 until it gets picked up and reduces NADP+ to NADPH. As the electron travels through the system of the light-dependent reactions, it provides enough energy for H+ ions to travel from the stroma to inside the thylakoid. From here an electrochemical gradient is produced and the H+ ions travel through the enzyme ATP Synthase to produce ATP from a reaction known as chemiosmosis.

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.
