Read the statement from leonid brezhnev.

each communist party is responsible not only to its own people, but also to all the socialist countries, to the entire communist movement.

according to brezhnev’s statement, what is the responsibility of the soviet union?

to give economic aid to non-communist nations around the world

to intervene, if necessary, in support of other communist governments

to support a policy of détente, meaning that it will withdraw from the arms race

to ensure that all the countries of the world have communist governments

Correct

An example of this approach by Brezhnev can be seen in what happened in  Czechoslovakia in 1968.  Czechoslovakia's new leader, Alexander Dubcek, promoted reforms, and the people began to move away from communism. This became known as the "Prague Spring."   Seeing these actions as a threat to continued communist controlled, Brezhnev responded with force.  He sent 600,000 Soviet troops and put down any movement of revolution against communism in Czechoslovakia.
