AFCAT Model Paper 7

NRADSIE → SARDINE → a type of fish.
GHBUELITT → TUBELIGHT → a device that is used to generate light.
AGTNEERRO → GENERATOR → a device used to generate electricity.
ORREGUTLA → REGULATOR → a device used to control the flow of electricity.
Clearly, NRADSIE is not related to electricity and is the odd one out.
