If the length of the perpendicular drawn from the origin to the line whose intercepts on the axes are `a` and `b` be `p`, then
(A)   `a^2+b^2=p^2`   
(B)   `a^2+b^2=1/p^2`   
(C)   `1/a^2+1/b^2=2/p^2`   
(D)   `1/a^2+1/b^2=1/p^2`   

A

`a^(2) +b^(2) =p^(2)`

B

`a^(2)+ b ^(2) =(1)/(p^(2))`

C

`(1)/(a^(2))+(1)/(b ^(2))=(2)/(p^(2))`

D

`(1)/(a^(2)) +(1)/(b ^(2)) =(1)/(p^(2))`
