Option B 2s orbital
![eduncle-logo-app]()
In case of 2s-orbital, number of nodes = 2-1 = 1. Thus it has two maxima separated by a region of a nodal surface. The probability density is maximum near the nucleus and decreases sharply to zero and then start increasing again and after reaching a maxima falls abruptly.
