Answer 1

A) This is a combination. Bands A, B and C look as pretty clear and defined but D and E look as blurry and hard to distinguish. Thats why it is a combination.

B) No, I dont think all the samples could have come from the same source. Standard sample is different from the other samples being investigated.
