Flow-through a divergin section is the right answer.

Pressure through a converging section increases in supersonic conditions. Decreases otherwise.

Flow through a diverging section should be the answer.

So, in this case it should be option D.

In converging section area is greater at the start so is pressure and as flow passes through small area pressure is lower in that region. Flow is actually from higher pressure to lower pressure how option B can be the answer?
