The Relative Proportions of Hydrogen and Helium That the Galileo

The relative proportions of hydrogen and helium that the Galileo Probe found in the atmosphere of Jupiter were almost exactly the same as in the Sun (as was expected) , but the noble gases argon, krypton, and xenon were three times as abundant in Jupiter's atmosphere than in the Sun's. Which of the following ideas is considered to be a possible reason for this?

A) Jupiter formed farther out from the Sun than it is now, where temperatures are colder.
B) Jupiter formed closer to the Sun than it is now, where temperatures were warmer.
C) The noble gases do not combine with any other elements and floated to the "surface" (atmosphere) of Jupiter.
D) The probe probed an anomalous region where abundances were abnormal compared to the rest of Jupiter.
