Answer:

D

Explanation:

The plants in the light formed bubbles because they released oxygen gas, This is because bubbles that are formed takes the places of oxygen molecules O2. Oxygen is released during photosynthesis through the process called light-dependent reaction.  The light-dependent reaction occurs only in the presencee of light. So, if bubbles formed are equivalent to oxygen molecules released in light-dependent reaction, then it is expected for bubbles to be found only on the leaves on those plants that were in a well-lit room.
