Which statement describes how a generated route determines its next hop?

A generate route is a specialized type of Junos summary route that, unlike an aggregate route, is permitted to inherit and use an actual forwarding next hop rather than being restricted to reject or discard. When multiple contributing routes exist beneath the summarized prefix, Junos selects one of them as the primary contributor using a deterministic process: it first evaluates route preference (choosing the contributor with the lowest, most preferred value), then breaks any remaining tie by preferring the contributing route with the numerically lowest metric, and continues through further tie-breaking criteria if necessary until a single primary contributor is identified. The generate route then adopts the next hop of that specific primary contributor as its own forwarding next hop, meaning traffic matching the generate route but not matching any individual contributing route is forwarded toward whichever real next hop the primary (best) contributing route currently uses. This behavior is fundamentally different from an aggregate route, which never adopts a forwarding next hop at all and instead installs with a reject (or optionally discard) next hop by default, deliberately preventing traffic from being forwarded toward a next hop that might not actually lead to the intended more-specific destination. There is no mechanism by which the next hop is chosen arbitrarily from the 'first' or 'least-specific' contributor, and while a next hop can be manually overridden under the generate route's own configuration, that is not the default resolution behavior being described here.
