(a) metal oxides with high temperature coefficient of
resistivity
(b) metals with high temperature coefficient of resistivity
(c) metals with low temperature coefficient of resistivity
(d) semiconducting materials having low temperature
coefficient of resistivity

Answer 1

d) semiconducting materials having low temperature

I hope it helps you

Answer 2

Answer:

silicon

Explanation:

Most transistors are made from very pure silicon, and some from germanium, but certain other semiconductor materials are sometimes used. A transistor may have only one kind of charge carrier, in a field-effect transistor, or may have two kinds of charge carriers in bipolar junction transistor devices.
