Three elements B, Si and Ge are
(a) metals
(b) non-metals
(c) metalloids
(d) metal, non-metal, and metalloid respectively

Solution: The answer is (c) metalloids

Explanation: Metalloids include the elements boron (B), silicon (Si), and germanium (Ge). Arsenic (As), antimony (Sb), tellurium (Te), polonium (Po), and astatine are some of the other elements (At). These elements are located in the periodic table between the metals and the non-metals group. They exhibit properties that are similar to those of both metals and nonmetals.
