A nonconducting sphere of radius R is filled with uniform volume charge density $-\rho$. The center of this sphere is displaced from the origin by $\overrightarrow{d}$. The electric field $\overrightarrow{E}$ at
any point P having position vector inside the sphere is

• A

  $\frac{\rho }{3{\epsilon }_0}\overrightarrow{d}$

• B

  $\frac{\rho }{3{\epsilon }_0}(\overrightarrow{r}-\overrightarrow{d})$

• C

  $\frac{\rho }{3{\epsilon }_0}(\overrightarrow{d}-\overrightarrow{r})$

• D

  $\frac{\rho }{3{\epsilon }_0}\left(\overrightarrow{r}\right)$
