Which Is NOT a Reason That Silicon Is Unsuitable as a Building

Which is NOT a reason that silicon is unsuitable as a building block for life compared to carbon?

A) silicon-silicon bonds are much weaker than carbon-carbon bonds
B) silicon does not form multiple bonds with itself, limiting the complexity of molecules it can form
C) silicon does not bond with many other elements
D) silicon dioxide is a high melting point solid and, hence, cannot be used to transfer silicon atoms like gaseous carbon dioxide can be used to transport carbon atoms
