Final answer:
The marine virus Elminia huxleyi virus releases dimethyl sulfide (DMS) when infecting plankton, resulting in enhanced cloud formation. Therefore correct option is D
Step-by-step explanation:
When the marine virus Emiliana huxleyi virus infects plankton, it results in enhanced cloud formation by releasing dimethyl sulfide (DMS) into the atmosphere. DMS is produced as a consequence of bacteria eating a chemical called dimethylsulfoniopropionate (DMSP), which is produced by dinoflagellates like Emiliana huxleyi. DMS is thought to be highly significant to global climate because it triggers cloud formation.
