Two statements 'A' and 'R' are given below Select your answers to these items using the codes given below: Assertio (A) : Among the cobalt (III) complexes [Co(NH_(3))_(6)]^(3+) is a diamagnetic but [CoF_(6)]^(3-) is paramagnetic. Reason (R) : Hybridisation of [Co(NH_(3))_(6)]^(3+) is sp^(3)d^(2) where as hybridisation of Co in [CoF_(6)]^(3-) is d^(2)sp^(3) .
