View answer and explanation

Correct option: C

\frac{1}{3} \log \left(e^x-1\right)-\frac{1}{3} \log \left(e^x+2\right)+c

Option A is correct because the integral is solved by multiplying the numerator and denominator by

e^x

, then substituting

t = e^x

, and using partial fraction decomposition.
