Hi all while solving one of the mocks following question come on messaging

In publish/subscribe architecture publisher send messges to
1) Specified node which is then redistributed to all subsribers.
2)Directly to all subscribers in topic subscribers list.
3)a designed queue.

Correct answer is 1) but i think correct answer sholud be 2)

What do all think about it ?

The correct answer is 1. The publisher publishes a message to a topic, which is redistributed by the message server to all of the topic's subscribers.
