Consider a n-type semiconductor in which $\displaystyle \mathrm{n}_{\mathrm{e}}$ and $\displaystyle \mathrm{n}_{\mathrm{h}}$ are number of electrons and holes, respectively.
(A)
Holes are minority carriers
(B)
The dopant is a pentavalent atom
(C)
$\displaystyle \mathbf{n}_{\mathbf{e}} \mathbf{n}_{\mathbf{h}} \neq \mathbf{n}_i^2$
(where $\displaystyle \mathrm{n}_i$ is number of electrons or holes in semiconductor when it is intrinsic form)
(D)
$\displaystyle \mathrm{n}_{\mathrm{e}} \mathrm{n}_{\mathrm{h}} \geqslant \mathrm{n}_i^2$
(E)
The holes are not generated due to the donors
