Consider the transportation analogy in Section 5.1.1. If the passenger is analagous to a datagram, what is analogous to the link layer frame?

The transportation mode(like train,car,bus) is analogous to the link layer frame, when passenger is analogous to a datagram.

Beacuse in link layer protocol, frame is the unit of transmission which transmits datagram between nodes.
