The Polymers Containing Silicon Differ from Polymers of Carbon in Which

The polymers containing silicon differ from polymers of carbon in which of the following ways?

A) Silicon-based polymers are larger molecules than carbon-based polymers.
B) Silicon-based polymers generally have a repeating silicon-oxygen link while carbon-based polymers can have carbon-carbon links.
C) Silicon-based polymers generally have inorganic elements attached to the chain while carbon-based polymers generally have organic groups attached.
D) Silicon-based polymers tend to be rigid while carbon-based polymers are generally flexible.
E) Silicon forms stronger bonds than carbon.
