Unicast transmission is defined as sending data from one sender to a single receiver.

Unicast transmission means sending data from one sender to exactly one receiver. This is a one-to-one delivery: the source uses a single destination address, and the network routes the packets specifically to that host. This is different from multicast, which targets a group of receivers, and broadcast, which goes to all hosts on a network segment. So the statement is correct because unicast is defined by its one-to-one delivery to a single recipient. The other options don’t fit: false would contradict the defined one-to-one nature, sometimes would imply variability that unicast does not have, and not defined would ignore the explicit meaning of unicast.
