The correct answer is option D. All three bulbs will go out.

In the circuit, all the bulbs are connected in series with each other. When the switch at C is opened, the circuit is broken (consider the wire is broken). It is shown in diagram as well (attached).

Hence, when the circuit is broken, the current will not reach the bulbs 2 & 3. And, the connection will be disrupted, So all the bulbs will blow out.

Hence, D is the correct option.
