Show answer & explanation
Correct answer: C
A rootkit is malicious software designed to gain unauthorized administrative (root) access to a system while hiding its presence. It alters OS functionality and allows the attacker to act as the system administrator. Other malware types like spyware, viruses, or trojans do not specifically match this definition of gaining full administrative control and hiding.
