Why each option

A Trojan horse is malicious code disguised as a legitimate program that can grant attackers unauthorized backdoor access to a compromised system.

AIt is a macro or script that attaches itself to a file or template.

Attaching to files or templates is the behavior of a macro virus, not a Trojan horse, which is a standalone deceptive program.

BThe writers of a Trojan horse can use it later to gain unauthorized access to a computer.Correct

A core characteristic of Trojan horses is the inclusion of a remote access or backdoor component, allowing the attacker to later reconnect and execute commands on the victim's machine without authorization.

CIt is a malicious software program code that resembles another normal program.Correct

By definition, a Trojan horse masquerades as a normal, benign application to trick the user into executing it, while secretly carrying a malicious payload.

DIt infects the boot record on hard disks and floppy disks.

Infecting the boot record is the defining behavior of a boot sector virus, a completely different malware category.
