Given the following sequence of reaction
`CH_(3)CH_(2)I overset(NaCN)(rarr) A underset(("Partial"),("Hydrolysis"))overset(OH^(-))(rarr)B overset(Br_(2)//NaOH)(rarr)C`
The major product 'C' is

Options

A. `CH_(3)CH_(2)NH_(2)`
B. `CH_(3)CH_(2)underset(O)underset(||)(C)-NHBr`
C. `CH_(3)CH_(2)-COONH_(4)`
D. `CH_(3)CH_(2)underset(O)underset(||)(C)=NBr_(2)`

Answer

A
