Silicon is sometimes mentioned a possible alternative to carbon in building biological molecules because _________________________.
A) it forms the basis of some life forms on Earth
B) it has a similar abundance on Earth to carbon
C) it forms complex molecules like carbon
D) it has a similar electronic structure to carbon, forming a maximum of four bonds and, hence, should have a similar chemistry
