Solution

The correct option is B Having light cytoplasm and small nuclei
The quiescent centre is a group of cells (approximately 1000), in the form of a hemisphere, towards the root tip. It is located at the centre of the meristem. These cells have lower division rate than that in the surrounding meristem. It is characterized by the presence of inactive cells with less number of cell organelles, light cytoplasm, small nuclei and low synthesis of DNA, RNA and protein.
