Division of cocci in three planes results in formation of:

Explanation

The correct answer is Sacrinae because when cocci undergo division in three planes, they form a cubic arrangement of 8 cells. This is distinct from the other options: Tetrad occurs with division in two planes, creating a square of 4 cocci; Staphylococcus arises from random divisions resulting in irregular clusters; and All of the above is incorrect because not all arrangements are produced by division in three planes.
