A spherically symmetric charge distribution is considered with charge density varying as \(\rho(r)=\left\{\begin{array}{ll}\rho_{0}\left(\frac{3}{4}-\frac{r}{R}\right) & \text { for } r \leq R \\ \text { Zero } & \text { for } r>R\end{array}\right.\) Where, \(r ( r < R )\) is the distance from the centre \(O\) (as shown in figure). The electric field at point \(P\) will be.

1. A \(\frac{\rho_{0} r}{4 \varepsilon_{0}}\left(\frac{3}{4}-\frac{r}{R}\right)\)
2. B \(\frac{\rho_{0} r}{3 \varepsilon_{0}}\left(\frac{3}{4}-\frac{r}{R}\right)\)
3. C \(\frac{\rho_{0} r}{4 \varepsilon_{0}}\left(1-\frac{r}{R}\right)\)
4. D \(\frac{\rho_{0} r}{5 \varepsilon_{0}}\left(1-\frac{r}{R}\right)\)
