Correct option is B
Explanation-
According to the ICN (Shenzhen Code, 2017):
The ICN governs the naming of Algae, Fungi, Plants, Fossils of algae, fungi, and plants
It explicitly excludes Prokaryotes (bacteria and archaea), Microsporidia (fungus-related parasites – treated under zoological code) and Animals
Option B - All algae and fungi along with their fossils, except Microsporidia
Correct — This matches the Shenzhen Code:
Includes algae and fungi and includes their fossils but excludes Microsporidia, which are parasitic and fall under zoological codes
Incorrect options-
Option A - Prokaryotes together with all algae and fungi, except their fossils
Prokaryotes are not governed under the ICN.
Option C -Prokaryotes and algae, except Microsporidia
Again, prokaryotes are excluded from ICN.
Option D - Photosynthetic algae and fungi
Partially correct but incomplete — ICN includes all algae, not just photosynthetic ones, and it also includes fossils.
Correct Answer: Option B
"All algae and fungi along with their fossils, except Microsporidia."
