If an insulated non-conducting sphere of radius \( R \) has charge density \( \rho \). The electric field at a distance \( r \) from the centre of sphere \( (r<R) \) will be
(a) \( \frac{\rho R}{3 \varepsilon_{0}} \)
(b) \( \frac{\rho r}{\varepsilon_{0}} \)
(c) \( \frac{\rho r}{3 \varepsilon_{0}} \)
(d) \( \frac{3 \rho R}{\varepsilon_{0}} \)
