I had been asked this question in a job interview.

The question is from Interacting with MySQL topic in chapter General MySQL Use of MySQL

Answer 1

The correct choice is (c) undoes last change

For explanation: Control-_ undoes the last change that was made. This can be repeated. The mysql input editor has a variety of commands to facilitate editing while providing inputs to the command line itself.
