If `x_(1),x_(2) "are two solutions of" X^(lnx^(2) )=e^(18) "then product of" X_(1)X_(2)` can be equal to
A. `(sec^(2)theta+co s ec^(2)theta)/(sec^(2)theta.c os ec^(2)theta)`,(wherever defined)
B. `(cot^(2)18^(@)-cvos^(2)18^(@))/(cost^(2)18^(@)cot^(2)18^(@))`
C. `sec 0+sec((pi)/(5))+sec((2pi)/(5))+sec((3pi)/(5))+sec((4pi)/(5))`
D. `2log6^(3).3^(log6^(3))^(-1)`
