ll. Nitrates
lll. Phosphates

a. l only
b. l and ll only

Explanation:

Algae are plant-like protists capable of photosynthesis in their cells (chloroplast). Like every other living organism that grows and reproduce, algae also requires nutrients for these processes to effectively occur.

Algae makes use of inorganic nutrients including sulphates, phosphates, nitrates etc which are found in fertilizers, detergents etc. In the presence of these compounds, algae tends to grow excessively to form a BLOOM. Hence, according to the question, nitrates and phosphates are the two inorganic nutrients algae makes use of.
