Planting the virus 'Trojan Horse' in computer network is

(i) Hacking (ii) Tampering
(iii) Decryption (iv) Intrusion

  • A.(i), (iii) and (iv) are correct
  • B.(ii), (iii) and (iv) are correct
  • C.(i), (ii) and (iii) are correct
  • D.(i), (ii) and (iv) are correct

Answer: B

The key says that planting the 'Trojan Horse' virus in a computer network is tampering, decryption and intrusion, so the answer is B.

A Trojan horse is a program that looks harmless but enters the system, alters or tampers with data, and opens the way for an unauthorised person to get in. In the key these are the three terms (ii), (iii) and (iv).

The key does not accept hacking (i), the term for breaking into a system by a person, so options A, C and D are rejected.
