Answer : The correct option is, boron (B), germanium (Ge), and tellurium (Te)
Explanation :
Metalloids : These are the elements that shows both the property of metals and non-metals.
For example : Boron, silicon, germanium, arsenic, antimony, tellurium, polonium and astatine are the metalloids.
As per question, the option boron, germanium and tellurium are the elements of metalloids.
Arsenic (As), sulfur (S), and polonium (Po) : In this option, arsenic and polonium are the metalloids but sulfur is a non-metal.
Polonium (Po), aluminum (Al), and silicon (Si) : In this option, polonium and silicon are the metalloids but aluminium is a non-metal.
Antimony (Sb), tellurium (Te), and gallium(Ga) : In this option, antimony and tellurium are the metalloids but gallium is a non-metal.
Hence, the correct option is, boron (B), germanium (Ge), and tellurium (Te)
