Solution
The correct option is B Metalloids
Metalloids have properties intermediate to that of metals and non-metals. They can act like a metal or a non-metal. The chemical reactivity of metalloids depends on the substance they react with.
For example; when boron reacts with sodium, it acts as a non-metal and on reaction with fluorine, it acts like a metal.
