Let’s examine each airline-slogan pair:
(A) Go Air – Fly Smart: Correct slogan.
(B) Jet Airways – The Joy of Flying: Correct. This has been their consistent branding.
(C) Air India – Fly the Good Times: Incorrect. This slogan actually belongs to Kingfisher Airlines. Air India uses “Air India – Truly Indian.”
(D) SpiceJet – Flying for Everyone: Correct. This is indeed the actual branding slogan.
Therefore, option (C) is wrongly matched.
