`C` and `Si` both have same lattice structure, having `4` bonding electrons in each. However, `C` is insulator whereas `Si` is intrinsic semiconductor. This is because

A

In case of `C` the valence band is not completely filled at absolute zero temperature

B

in case of `C` the conduction band is partly filled even at absolute zero temperature

C

the four bonding electrones in the case of `C` lie in the second orbit, whereas in the case of `Si` they lie in the third

D

the four bonding electrons in the case of `C` lie in the third orbit, whereas for `Si` they lie in the fourth orbit
