f(x)=\left(\frac{x^a}{x^b}\right)^{a+b} \cdot\left(\frac{x^b}{x^c}\right)^{b+c} \cdot\left(\frac{x^c}{x^a}\right)^{c+a}

then

f^{\prime}(x)

is equal to

View answer and explanation

Correct option: B

Option B (0) is correct because after simplification, f(x) becomes 1, and the derivative of a constant is 0.
