A function `f(x)` is defined in `a lt x lt b` and `a lt x_(1) lt x_(2) lt b`, then `f(x)` is strictly monotonic decreasing in `a le x le b` when-

A

`f(x_(2)) gt f(x_(1))` when `x_(2) gt x_(1)`

B

`f(x_(2)) lt f(x_(1))` when `x_(2) gt x_(1)`

C

`f(x_(2)) gt f(x_(1))` when `x_(2) lt x_(1)`

D

`f(x_(2)) lt f(x_(1))` when `x_(2) lt x_(1)`
