A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -DO ALGAE LIVE ONLY IN WATER? Most species of algae live in the sea, in lakes, or in ponds. Some single-celled green algae live in moist conditions on land, such as on tree trunks, on the surface of the soil, or on damp brickwork. Others live inside lichens.

Detailed explanation-2: -Toxic blue-green algae prefer warmer water. Warmer temperatures prevent water from mixing, allowing algae to grow thicker and faster. Warmer water is easier for small organisms to move through and allows algae to float to the surface faster.

Detailed explanation-3: -Algae are simple plants that live in oceans, lakes, rivers, ponds, and moist soil. Algae grow in many forms. Some are microscopic and consist of just one cell and others are made up of many cells that form strands or colonies. Algae are more simple than aquatic plants as they lack a true root, leaf, and stem system.

Detailed explanation-4: -Lastly, algae are found in a range of aquatic habitats, both freshwater and saltwater. By virtue of these characteristics, the general term “algae” includes prokaryotic organisms-cyanobacteria, also known as blue-green algae-as well as eukaryotic organisms (all other algal species).
