How many nodal planes do d x2- y2 have?1)12)23)04)none

Here option 4 is none of these .now as per i think the electron density is minimum at axis x-y=0 and x+y=0so nodal planes will lie along these axis .d x^2-y^2 do not have axial nodal planes but have non axial nodal planes as mentioned before so please clear my doubt

Angular nodes can be of two types nodal planes and nodal cones this orbital has 2 nodal cones and no nodal plane
