323297 Match Column I with Column II and choose the correct combination from the options given.

323298 Assertion :
With \(\mathrm{Br}_{2}-\mathrm{H}_{2} \mathrm{O}\), phenol gives \(2,4,6-\) tribromophenol but with \(\mathrm{Br}_{2}-\mathrm{CS}_{2}\), it gives 4-bromophenol as the major product.
Reason :
In water, ionisation of phenol is enhanced but in \(\mathrm{CS}_{2}\), it is greatly suppressed.
