A - A Trojan horse.

Explanation:

As the exercise briefly states, a trojan horse is a program in which malicious code is hidden inside a seemingly harmless program. It's named after the mythical siege of Troy, where a giant horse was created to hide soldiers in it and then left in the doors of Troy, as a "parting gift" from the greek attackers.
