What is other name of GOKU??

In the Dragon Ball series, Goku's original Saiyan birth name is Kakarot (or Kakarrot), which is phonetically similar to 'Kakkrot' as given in option A. This is his Saiyan name given by his biological parents Bardock and Gine. Vegeta consistently calls him Kakarot throughout the series as a reminder of their Saiyan heritage. 'Gokkarot', 'Raditz', and 'Gojeto' are incorrect.
