Why each option

Worms and Trojan horses differ in their self-replication behavior. Worms autonomously replicate and spread across networks, while Trojan horses disguise themselves as legitimate software but do not self-replicate.

ATrojan horses are a form of malicious codes while worms are not.

Both worms and Trojan horses are forms of malicious code (malware), so this distinction is factually incorrect.

BTrojan horses are harmful to computers while worms are not.

Both worms and Trojan horses are harmful to computers - worms consume bandwidth and system resources while Trojans can create backdoors or deliver payloads.

CWorms can be distributed through emails while Trojan horses cannot.

Both worms and Trojan horses can be distributed via email attachments or links, so this is not a distinguishing characteristic.

DWorms replicate themselves while Trojan horses do not.Correct

Worms are specifically defined by their ability to self-replicate and propagate across systems without user interaction, whereas Trojan horses rely on social engineering to be executed and do not copy themselves to other systems.
