Why each option

To reuse an old password when a system's password history policy is set to remember three previous passwords, an engineer must change the password a total of four times. This action cycles the desired old password out of the remembered history, assuming each change respects the minimum password age of two days.

AChange the password four times.

Changing the password only two times would likely not clear enough entries from the password history to allow reuse of an older password, assuming a standard password history policy of remembering multiple previous passwords.

BChange the password two times.

Changing the password only two times would likely not clear enough entries from the password history to allow reuse of an older password, assuming a standard password history policy of remembering multiple previous passwords.

CChange the password four times.Correct

To reuse an old password when a system's password history policy is typically set to remember three previous passwords, an engineer must change the password a total of four times with unique values. This action cycles the desired old password out of the remembered history, making it available for reuse on the fourth change, assuming each change respects the minimum password age of two days.

DChange the password six times.

Changing the password six times would push the desired old password out of history long ago, which is an excessive number of changes if the goal is to reuse a password within a typical three-password history.
