If `sec theta= a/b, b ne 0`, then `(1-tan^2 theta)/(2-sin^2 theta)`= ?
यदि `sec theta= a/b, b ne 0`, तो `(1-tan^2 theta)/(2-sin^2 theta)`= ?

A

`(b^(2)(2b^(2)-a^(2)))/(a^(2)(a^(2)+b^(2)))`

B

`(a^(2)(2b^(2)+a^(2)))/(b^(2)(a^(2)+b^(2)))`

C

`(a^(2)(2b^(2)-a^(2)))/(b^(2)(a^(2)+b^(2)))`

D

`(a^(2)(2b^(2)+a^(2)))/(b^(2)(a^(2)-b^(2)))`
