Solution

The correct option is B $C H_{3} C H_{2} C O O H + C O_{2} + H_{2} O$
option C must be the right answer.
Terminal Alkynes like 1-butyne in the presence of $K M n O_{4}$ under basic conditions forms 1-propionic acid and water.
$C H_{3} C H_{2} C \equiv C H \to C H_{3} C H_{2} C O O H + C O_{2} + H_{2} O$
