Figure EP 10.5 shows a standard two slit arrangement with slits `S_1`, `S_2`, `P_1`, `P_2` are the two minima points on either side of P.
At `P_2` on the screen, there is a hole and behind `P_2` is a second 2-slit arrangement with slits `S_3`, `S_4` and a second screen behind them.

A

(a) There would be no interference pattern on the second screen but it would be lighted.

B

(b) The second screen would be totally dark.

C

(c) There would be a single bright point on the second screen.

D

(d) There would be a regular two slit pattern on the second screen.
