AFCAT Model Paper 1

Let’s unjumbled the given options:
(1) TGMAINSRA ⇒ INSTAGRAM
(2) BILEMO ⇒ MOBILE
(3) BKFOCEOA ⇒ FACEBOOK
(4) HTWSPAPA ⇒ WHATSAPP
Thus, MOBILE is not an application but a device whereas INSTAGRAM, FACEBOOK and WHATSAPP are social networking applications.
Hence, BILEMO is the odd one out.
