Two system of rectangular axes have the same origin. If a plane cuts them at distance a,b,c and a', b' , c' from the origin , then :

Options

A. `1/(a^(2)) + 1/(b^(2))+ 1/(c^(2)) - 1/(a^(2))-1/(b^(2)) -1/(c^(2)) = 0`
B. `1/(a^(2)) + 1/(b^(2))+ 1/(c^(2)) + 1/(a^(2))+1/(b^(2)) +1/(c^(2)) = 0`
C. `1/(a^(2)) + 1/(b^(2))- 1/(c^(2)) + 1/(a^(2))+1/(b^(2)) -1/(c^(2)) = 0`
D. `1/(a^(2)) - 1/(b^(2))- 1/(c^(2)) - 1/(a^(2))-1/(b^(2)) -1/(c^(2)) = 0`
