B) Simplex
C) Full-duplex
D) Asynchronous

Simplex transmission is one-directional, meaning data is only transmitted in one direction. However, it is relatively uncommon in data transmissions since most devices, even if they are primarily one-directional, are still capable of transmitting other data back to the computer, such as error messages. Therefore, half-duplex or full-duplex transmission is typically used in data transmissions. Asynchronous transmission, on the other hand, refers to a type of data transmission where each character is transmitted independently of the others, without a clock signal to synchronize the communication.
