A team of astrophysicists has detected a series of unusual radio signals from a distant star system. The signals follow a repeating mathematical pattern that does not occur naturally in known cosmic phenomena. Based on this, the scientists conclude that the signals are likely of extraterrestrial intelligent origin.
Which of the following, if true, most seriously weakens the scientists’ conclusion?
(A) The same type of signal has been detected coming from multiple star systems with no known habitable planets.
(B) The radio signals are much weaker than those previously speculated to be possible extraterrestrial communications.
(C) The mathematical pattern observed in the signals is identical to those generated by certain types of pulsars under specific conditions.
(D) The scientists have not yet decoded the meaning of the signals or determined their exact source.
(E) A team of researchers on Earth recently developed an AI system capable of generating similar signals for deep-space communication experiments.

Could I ask why A is wrong? I see how C could be right. I figured A might be more direct because it shows that the researchers' conclusion isn't the most coherent because we have heard such unusual sounds before, and did not come to the conclusions there must be alien life.
My thinking for why C might be correct is that the researchers' premise for this reasoning is actually the mathematical equations, NOT the unusual sound. So we want to knock the validity of the mathematical pattern.

I guess the answer is B as the radio signals are not in coherence with the earlier speculated ET signals. "The radio signals are much weaker than those previously speculated to be possible extraterrestrial communications.
