What is the relation between the planes a1x + b1y + c1z + d1 = 0 and a2x + b2y + c21z + d2 = 0, if their normal are perp

a) a1a2 . b1b2 . c1c2 = 0
b) a1a2 + b1b2 + c1c2 = 0
c) a1a2 + b1b2 – c1c2 = 0
d) a1a2 + b1b2 – c1c2 = 0
b) a1a2 + b1b2 + c1c2 = 0
c) a1a2 + b1b2 – c1c2 = 0
d) a1a2 + b1b2 – c1c2 = 0
