Which of the following pairs of elements belong to the same group?

A. (H) & (He)

B. (Li) & (Be)

C. (C) & (Pb)

D. (Ga) & (Ge)

Carbon and Lead make the most sense

Explanation:

None of them are in the same group but carbon and lead are in the same column. Hydrogen is an other non-metal and Helium is a noble gas, Lithium is an Alkali metal and Beryllium is an Alkaline earth metal, Carbon is an other non-metal and Lead is a Post-transition metal, Gallium is Post-transition metal and Germanium is a Metalloid. So none of the pairs are in the same group, but carbon and lead do share the same column.
