f\left( x \right) = \frac{1}{{1 - x}},

then the derivative of the composite function

f\left[ {f\left\{ {f\left( x \right)} \right\}} \right]

is equal to

View answer and explanation

Correct option: C

Option C (1) is correct because after simplifying the composite function f[f{f(x)}] it results in x, and the derivative of x is 1.
