Line `L` has intercepts `a` and `b` on the coordinate axes. When, the axes area rotated through a given angle, keeping the origin fixed, the same line `L` has intercepts `p` and `q`, then
A. `a^(2)+b^(2)=p^(2)+q^(2)`
B. `(1)/(a^(2))+(1)/(b^(2))=(1)/(p^(2))+(1)/(q^(2))`
C. `a^(2)+p^(2)=b^(2)+q^(2)`
D. `(1)/(a^(2))+(1)/(p^(2))=(1)/(b^(2))+(1)/(q^(2))`
