Answer:
C. He can trace the keystrokes used by his friend to log into his account, and then hack it.
Step-by-step explanation:
A keylogger can be defined as a software program or hardware device designed for monitoring and recording the keystrokes entered by an end user through the keyboard of a computer system or mobile device. A keylogger can be installed as a software application or plugged into the USB port of a computer system, so as to illegally keep a record of all the inputs or keys pressed on a keyboard by an end user.
In this scenario, Ramsay sent a keylogger spyware to his friend's computer. Thus, the likely consequence of this is that he can trace the keystrokes used by his friend to log into his account, and then hack it.
In order to prevent cyber hackers from gaining access to your keystrokes, you should install an anti-malware software application such as Avira, McAfee, Avast, Bitdefender, Kaspersky etc.
