In guided transmission media, signals are directed along a specific path by using: a. Physical medium b. Microwaves c. Radio waves d. Satellite links

a. Physical medium<br /><br />In guided transmission media, signals are directed along a specific path using a physical medium such as cables (e.g., twisted pair cables, coaxial cables, or fiber optic cables). These physical mediums provide a defined pathway for the signal to travel from the sender to the receiver.
