I have been asked this question in an interview for internship.

I want to ask this question from Telnet in section Application Layer of Computer Network

Answer 1

Correct choice is (b) Most text typed is immediately sent to the remote host for processing

For explanation: In character at a time mode, the typed text is sent immediately to the remote host while the user is typing. Another mode used in Telnet is “Old line by line” mode in which only completed lines are sent to the remote host.
