Answer:
The definition of intelligentsia is Option B. An intellectual elite.
Explanation:
This term describes a special class of people who are artists, intellectuals, teachers who can serve as cultural and political leaders in society because of their education and learned outlook. Historically, the term was used in Russian controlled Poland in the late 18th century and later in Russia before the Bolshevik Revolution. The idea was that this was a new but highly educated urban social class that could be a source of political and cultural influence, but they were also outside the typical monarchic social-classes (royalty, aristocracy, bourgeoisie).
