I think it’s A but I’m not sure.
Answer is: c) CAM.
CAM (crassulacean acid metabolism) is a carbon fixation pathway.
In plants with CAM carbon fixation, carbon dioxide is stored as the malic acid malate in vacuoles at night.
During the daytime, the malic acid is transported to chloroplasts where it is converted back to carbon dioxide, which is then used during photosynthesis.
Malic acid is an organic dicarboxylic acid with the molecular formula C₄H₆O₅.
Answer: Dipole-dipole forces: electrostatic interactions of permanent dipoles in molecules; includes hydrogen bonding.

Acid rain is formed by chemicals let off into the atmosphere further introducing the nitrogen oxides which are attached to the water vapour and than mixed together further making acid rain which contains a pH scale of 6 a pale light acid though very much effective.
