Which pain killer given to cattle is responsible for near extinction of vultures in India?

Correct answer: (d) Diclofenac

Explanation

Diclofenac is an anti-inflammatory painkiller once given to cattle.

Residues in carcasses caused kidney failure and visceral gout in feeding vultures, crashing their numbers by 97-99.9%.

India banned veterinary diclofenac in 2006; the other listed drugs are not the cause.
