D Correct answer
Explanation

Cadmium arsenide is a crystalline semiconductor with a tetragonal structure in the II-V family. It is a n-type intrinsic semiconductor. Cadmium arsenide is used in infrared detectors using Nernst effect, and in thin-film dynamic pressure sensors. It can also be used to make magnetoresistors, and finds use in in photodetectors.
