Answer: Option A.

Produced the oxygen in atmosphere

Explanation:

Photosynthetic prokaryotes have chlorophyll in their cytoplasm. The chlorophyll is join to protein to form chlorosome(light harvesting molecules) which in turn convert light energy to chemical energy and fixed carbon dioxide in the atmosphere by synthesizing light in sugar , thereby release oxygen to the atmosphere. The photosynthetic prokaryotes include cyanobacteria, algae e.t.c

Answer:

a) produced the oxygen in the atmosphere

Explanation:

Prokaryotes are likely to first form of life on earth and they existed billions of years ago before animals and plants.
As these prokaryotes can do photosynthesis so there most important function is produce oxygen in atmosphere for the evolution of aerobic life.
At that time the conditions were harsh on earth so these prokaryotes are used to survive under earth like in oceans. They first produce oxygen in oceans.
In eukaryotes photosynthesis emerge by endosymbiosis with photosynthetic prokaryotes.
