I got it right on EDG.2020
D is the rising magma, which is hot and is a molten rock.
B, as you can see, is an underwater volcano and is rising from the underground and the crater, vents, and fissures are inside the water.
A is a hotspot volcano, as it is present on the earth surface and is not an oceanic volcano.

Answer:
b) Proteins: decrease
Explanation:
Out of all the biomolecules required for the survival of an organism, proteins and nucleic acids are the ones containing Nitrogen. In nucleic acids, the building blocks of DNA, nitrogen is present in the nitrogenous bases, which are Adenine, Guanine, Cytosine, Thymine, and Uracil. In the proteins, the amino acids contain the amine group or -NH₂ which forms the peptide bond (-NH-CO-) with a carboxylic group or -COOH of the next amino acid. As the culture of <em>Spirogyra </em>is being maintained, there would be no replication of DNA, which would have required nitrogen to synthesize the new DNA strand. But, to synthesize proteins, the RNA synthesis would require to happen which would also require nitrogen. Moreover, the formation of proteins after the translation of the mRNA would have also required Nitrogen. Thus, protein level in the cells would decrease.
