Solution

The correct option is B $N a O H, I_{2} / H^{+}$
$C H_{3} - C H_{2} - O | | C - C H_{3} B u t a n - 2 - o n e + 3 I_{2} + N a O H \to C H I_{3} + C H_{3} - C H_{2} - O | | C - O N a H^{+} - - \to C H_{3} C H_{2} - O | | C - O H p r o p a n o i c a c i d$

Butan-2-one when reacted with $N a O H, I_{2}$ , it undergoes haloform reaction to form Iodoform along with the sodium propionate.

This sodium propionate is then reacted with $H^{+}$ to form propionic acid as a product.
