Which statement is true about a polarized object?

a) it gains electrons and becomes negatively charged.
b) it gains protons and becomes positively charged.
c) the number of positive and negative charges can be the same.
d) it has to be a metal.
e) there is no change in the distribution of the charge in the object.

Option C: The number of positive and negative charges can be same.

A substance is said to be polarized when there is non-uniform distribution of electric charge. When there gain or loss of electrons, ions are formed. It is not necessary that polarized object is metal. For example, Water is polarized. The oxygen atoms have partial negative charge and hydrogen atoms have partial positive charge.
