Answer:
d) A is false but R is true.
Step-by-step explanation:
Prokaryotes are group of organisms that do not possess a membrane bound nucleus or any other membrane bound organelle in their cell e.g. mitochondria, endoplasmic reticulum etc. They lack such organelles.
However, they are truly considered as a primitive life form; much more primitive than eukaryotic organisms. Examples of prokaryotes are bacteria, archeae etc. Based on the above explanation, it is clear that the assertion (A) in this question is FALSE but the reason (R) is TRUE.
