Explanation:

First Question (In Group 13 (Boron Family), what element is classified as a metalloid? )

In Group 13 (Boron Family), Boron (B) is a metalloid. Aluminum, Gallium, and Indium are metals. Metalloids have properties intermediate between metals and non - metals. Boron shows such intermediate properties, while the others are typical metals.

The chemical symbol for Antimony is Sb. Sn is the symbol for Tin, Al (not A as in the option, probably a typo) is for Aluminum, and Ant is not the chemical symbol for Antimony.

Answer:

Boron
