Solution

The correct option is E Boron
Group 13 (IIIA) consists of boron, aluminium, gallium, indium, and thallium.

Boron is a metalloid, but the other elements are metals. All elements in this group have three valence electrons.

All the elements in this group have 3 valence electrons in their valence shell.

Hence the correct option is E.
