The correct answer is B. I and III only.

Explanation:

I. Metals conduct electricity: This is true. Metals are good conductors of electricity because they have free electrons that can move easily.

II. Metals form acidic oxides: This is false. Metals generally form basic oxides, not acidic ones. Non-metals are the ones that typically form acidic oxides.

III. Metals react by losing electrons: This is true. Metals are electropositive elements, meaning they tend to lose electrons in chemical reactions. This is why metals typically form positive ions (cations).
