Solution

The correct option is B $C H_{3} C H_{2} O H$
When ethyl alcohol reacts with $P B r_{3}$ it forms ethyl bromide as a product which on reaction with alc KOH undergoes $β$ -elimination reaction to form ethene as a product. The ethene on reaction with dil. $H_{2} S O_{4}$ undergoes hydrolysis to form ethyl alcohol as a product.
Hence option $B$ is correct.
