Answer:

Explanation:

None of the other answers matter but the right answer which A. Silicon has an outer shell of 4. Carbon can connect with 4 elements  because of its outer shell. CH4 is the simplest example. But C2H6 is also possible.

     H   H

H - C - C - H

     H   H

There are 4 connections to the outside world for the Carbon (C) on the left.

It has 3 hydrogens connected on to it and one of its connecting electrons goes with the other carbon on the right.

Silicon can do the same thing.
