Which option enables OS detection, version detection, script scanning, and traceroute in a single scan?

• A. -D
• B. -O
• C. -A
• D. -sV

Answer: (C)

The right choice is the all-in-one switch that enables a complete fingerprint in one go. This single option turns on OS detection, version detection, script scanning, and traceroute together, giving you OS information, service versions, data from default scripts, and the network path to the host in one scan. That’s why it’s the best single-shot option for full discovery.

To see why the others don’t fit: one switch focuses on decoy scanning and doesn’t enable any of these fingerprinting features; OS detection only turns on OS fingerprinting; version detection only checks service versions; script scanning runs default scripts alone. Since the question asks for all four capabilities in a single scan, only the all-in-one switch satisfies it. For example, you’d run something like nmap -A target.
