The best reason why no bubbles were released during the first portion of the experiment, where the lights were turned off, is:

A. There was no light present for photosynthesis to occur.

Photosynthesis requires light as one of its essential components. Without light, the process cannot take place, which would explain the lack of bubbles (typically signifying oxygen production) during that time.
