detailed solution

Correct option is D

$Case II If x < 0, then | x | = - x$

$\begin{array}{l} ∴ \int | x | \log | x | dx = \int xlog xdx \\ = \log x \cdot \frac{x^{2}}{2} - \int \frac{1}{x} \cdot \frac{x^{2}}{2} dx \\ = \frac{x^{2}}{2} \cdot \log x - \frac{x^{2}}{4} + C = + \frac{x^{2}}{2} \log | x | - \frac{x^{2}}{4} + C \end{array}$

$Case II If x < 0, then | x | = - x$

$\begin{array}{l} ∴ \int | x | \log | x | dx = - \int xlog (- x) dx \\ = - \{\log (- x) \cdot \frac{x^{2}}{2} - \frac{x^{2}}{4}\} + C \\ = - \frac{x^{2}}{2} \log | x | + \frac{x^{2}}{4} + C \end{array}$
