The correct option is A Algae
One can clearly found algae in a waterbody as algae are found in a large range in aquatic habitats.
They are able to prepare their own food by the process of photosynthesis by the help of chlorophyll which gives green colour to algae.
Hence the green colour scum is visible over water bodies.
The correct answer is A.
