Videocon's famous tagline was 'Pack Jindagi Ka Har Signal' - incorrectly written as 'PAKDO LIFE KA HAR SIGNAL' in option C. The Hindi phrase means 'Catch every signal of life' and was part of Videocon's major marketing campaign. Note that option A 'KARLO DUNIYA MUTHI ME' is also a tagline but belongs to Airtel, not Videocon. Option B has 'JINDGI' instead of 'JINDAGI' making it incorrect.
