The correct response is:

Silicon has an outer shell of electrons that is similar to carbon.

Silicon is in the same group as carbon in the periodic table (group 14), which means it has similar chemical properties, including the ability to form four covalent bonds. This similarity leads scientists to consider the possibility of silicon-based life forms, particularly in environments that might not support carbon-based life.
