Picking D.
"compared to" is wrong. It shouldn't be used to compare two similar things.

selene, welcome back buddy...

agree with D because it needs "fainter than" to make the sentence logical and we cannot insert "compare to" in between "fainter" and "than". So A/B are out. also needs "those' cuz the comparision is between x sources and y sources.

compared to is wrong here, so A and B are out

C... "that" refers sources... incorrect
E... "detecting" is a gerund playing a verb role... NO-NO
