Answer:
Option (A) and (C)
Step-by-step explanation:
Green house gases are the gases which trap the heat from sunlight causing the retention of heat in the atmosphere. This causes global heat.
The use of natural light will reduce the dependency of fossil fuel for the generation of electricity. Hence, the burning of fossil fuel and generation of greenhouse gases such as carbon dioxide, carbon monoxide and others will not release.
Growing own vegetables will reduce the carbon dioxide levels in the atmosphere. Hence, will reduce the green house gas abundance in the atmosphere.
