Answer 2

The proud king turned a deaf ear to the advice of counsellors.

Explanation:

Advice is a word that means suggestion given as guidelines for one's action. The verb 'advice' explains the action in form of the noun.

Therefore, the advice is the right word to be used in the above sentence.

Also, as a collective noun (which refers to collection of things), advice does not take plural form, that is, it does not become 'advices'.
