Answer

Brief Explanations:

In photosynthesis, water ($H_2O$) is split and hydrogen enters plants as a component of water. Also, hydrogen along with carbon - dioxide is used to make glucose ($C_6H_{12}O_6$) through a series of reactions. Hydrogen is not stored in leaves in the context of photosynthesis as described in the first two options, and hydrogen combining with oxygen makes water not carbon - dioxide.

Answer:

1 - Hydrogen enters plants as a component of water. 2 - Hydrogen combines with carbon dioxide to make glucose.
