Solution

The correct option is C CH3CH2Br
The complete reaction sequence is as follows:

CH3CHOLiAIH4−−−−CH3CH2OHH+/1700C−−−−−CH2=CH2excessHBr−−−−−−CH3CH2Br

A is CH3CH2OH which is formed by reduction of the carbonyl group.

B is CH2=CH2 formed by the loss of water on heating.

C is CH3CH2Br formed by addition of HBr .

Option C is correct.
