I'm really surprised the school and the district doubled down when they were wrong. Even if light is not always generated by combustion, B is a less wrong answer than C, and it's pretty straightforward to establish that oxygen is consumed in a typical combustion, not produced. The school also erred in taking an adversarial tone over the photos the family took.
