Hall effect — CSIR Net PYQ (Question 2)

The Hall coefficient for a semiconductor having both types of carriers is given as
$R_H=\frac{p{\mu }_p^2-n{\mu }_n^2}{|e|{\left(p{\mu }_p+n{\mu }_n\right)}^2}$
where $p$ and $n$ are the carrier densities of the holes and electrons, ${\mu }_p$ and ${\mu }_n$ are their respective mobilities. For a $p$ -type semiconductor in which the mobility of holes is less than that of electrons, which of the following graphs best describes the variation of the Hall coefficient with temperature?
