Answer:
Option B, Silicon
Explanation:
The valency of Carbon is 4 as it has four electrons in its outermost shell
The valency of Si is also four hence C
Hence Silicon can form 1:1 bond with the carbon
Valency of Beryllium is 2, hence it can not form 1:1 bond with carbon. Similarly the valency of oxygen and carbon are way different to form 1:1 bond
hence, only option B is correct
