B)    No     ​

Answer 1

Answer:

A) Yes......................

Answer 2

Given:

The given statement is as follows:

LiNbO3 and PbZrO3 are examples of active dielectrics.

To Find:

The given statement is true or false.

Solution:

Lithium niobate ($LiNbO_3$) is a ferroelectric compound. It has been widely used in various devices because of its piezoelectric, pyroelectric,  electro-optic, photo-elastic, and dielectric properties.

So the given statement is true as it has the non-vanishing piezoelectric and

dielectric coefficients(once we look into these matrices:
