Which properties are characteristic of metalloids?

a. high electrical conductivity and a high melting point
b. low electrical conductivity and a low melting point
c. intermediate conductivity and a high melting point
d. intermediate conductivity and a low melting point

The right option is (C) intermediate conductivity and a high melting point

Metalloids usually look like metals but behave largely like nonmetals. Metalloids are shiny, brittle solids with intermediate good electrical conductivity. Their properties lie between metals and non metals. All metalloids exist as solids at room temperature and they have very high melting points. The physical properties of metalloids are more likely to be metallic, but their chemical properties tend to be non-metallic

Yes the answer is C.) intermediate conductivity and a high melting point
