Answer: None of the above
Step-by-step explanation:
Unguided physical media is basically use in the transmission of the electromagnetic wave and it does not use any physical medium for transmission. It is also known as wireless transmission.
Physical media for transmission uses various types of cables for the transmission like twisted pair cable, fiber optics and coaxial cable. These cables are typically use within the various types of building for transmission.
Therefore, unguided media does not use any type of physical media for the transmission so the answer is none of these.
