$\boxed{\fcolorbox{red}{pink}{Hence, the correct option is C}}$

In a group, electronegativity decreases as the size increases, which leads to the ability to attract electrons decrease. Thus, P<N and Si<C.

In a period, as the size decreases, electronegativity increases due to the increase in effective nuclear charge.

Thus, C<N and P<Si. Hence, the overall order is Si<P<C<N.

Hence, the correct option is C
