A)Both Types of Bonds Can Be Made

Which statement regarding $\sigma$ and $\pi$ bonds is TRUE?

A) Both types of bonds can be made by the overlap of unhybridized atomic orbitals.
B) The overlap of sp hybrid orbitals can form either a $\sigma$ or a $\pi$ bond.
C) When two atoms form a multiple bond, $\sigma$ and $\pi$ bonds overlap in space and reinforce each other.
D) Multiple bonds between atoms often involve only $\pi$ bonds, not $\sigma$ bonds.
E) Electron density cannot be localized between two atoms when they participate in $\pi$ bonding.
