The answer is (1) addition. The addition reaction means that two or more molecules combine together to form a large one, usually in organic reaction. According to the given equation, the best classified is addition.
Firstly, carbon isn't a metal.
Boron is a metalloid.
Beryllium is the least metallic alkaline earth metal, and lithium is the least metallic alkaline metal.
Both are metallic, and have metallic appearances and conduct electricity, but beryllium is more brittle than lithium.
So, I'd say Li and Be are equal.
