Answer & Solution
Correct Answer
(A) (A) - (II), (B) - (I), (C) - (IV), (D) - (III)
Step-by-step Solution
Detailed explanation
Germanium (A): A semiconductor with a relatively small band gap of approximately 0.7 eV. Silicon (B): The most common semiconductor, requiring slightly more energy at approximately 1.1 eV. Insulator (C): These materials have a very wide band gap (typically \(>3 eV\) ), making it…
