Let there be a spherically symmetric charge distribution with charge density varying as $\rho(r) = \rho_{_0}(\frac{5}{4} - \frac{r}{R})$ upto $r = R$ and $\rho (r) = 0$ for $r > R$, where $r$ is the distance from the origin. The electric field at a distance $r (r < R)$ from the origin is given by

Question

( A ) $\frac{\rho_0 r}{4 \varepsilon_0}(\frac{5}{3} - \frac{r}{R})$
( B ) $\frac{\rho_0 r}{3 \varepsilon_0}(\frac{5}{4} - \frac{r}{R})$
( C ) $\frac{4 \pi \rho_0 r}{3 \varepsilon_0}(\frac{5}{3} - \frac{r}{R})$
( D ) $\frac{4 \pi \rho_0 r}{3 \varepsilon_0}(\frac{5}{4} - \frac{r}{R})$
