I believe the correct answer from the choices listed above is the second option. Becquerel expose uranium crystals to sunlight in his initial experiment because he wanted to show that the crystals emit X-rays which would explain the patterns seen on the photographic plates exposed to uranium salts. Hope this answers the question.
