are

A
${Br}_{3} C - OH$ and
Correct answer
B
and ${CHBr}_{3}$
C
and $NaBr$
D
$PhH$ and ${CBr}_{3} {CO}_{2} Na$

Solution

and ${CHBr}_{3}$

Hint Reaction given is the last stage of haloform reaction.

${OH}^{-}$ nucleophile attacks carbonyl carbon, resulting in the leaving of ${CBr}_{3}^{-}$ .

Hence, the correct answer is option: 'B'.
