What is the major difference between link$-$state routing and distance$-$vector routing?

Question $2$ options:

Link state sends a portion of its route table to neighbor routers participating in the same network protocol.

Link state routers gather information from neighbor routers and then forward this route table to other routers. Eventually, all routers will have the same information.

Distance$-$Vector sends a portion of its route table to neighbor routers participating in the same network protocol.

Answers $2$ and $3$ are correct.
