Solution

The correct option is D Both the assertion and reason are false.
The granal membranes are enriched in PS-II and LHC (Light harvesting centre), while there is little ATP synthetase. On the other hand, only a fraction of stromal thylakoids are rich in PS I and ATPase and poor in PS-II and LHC.
