Two systems 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 :

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
