Discovered by astronomers in July 2010, R136a1 is the most massive star ever cataloged, 60 percent more massive than the theoretical limit at the time it was discovered, and the most luminous star known to humankind.
A: Discovered by astronomers in July 2010, R136a1 is the most massive star ever cataloged, 60 percent more massive than the theoretical limit at the time it was discovered, and the most luminous star known to humankind.
B: Discovered by astronomers in July 2010, R136a1, the most massive star ever cataloged, it was 60 percent more massive than the theoretical limit at the time it was discovered and was the most luminous star known to humankind.
C: When it was discovered by astronomers in July 2010, R136a1, the most luminous star known to humankind, was the most massive star ever cataloged, its mass exceeding the theoretical limit at the time by 60 percent. *
D: The most massive star ever cataloged in July 2010, when it was discovered by astronomers, R136a1 exceeded the theoretical limit by 60 percent and was the most luminous star known to humankind.
E: R136a1, the most massive star ever cataloged and the most luminous star known to humankind, was 60 percent more massive than the theoretical limit was at the time of discovery by astronomers in July 2010.
Can someone explain about option A?
Discovered by astronomers in July 2010,
R136a1 is the most massive star ever cataloged
R136a1 is 60 percent more massive than the theoretical limit at the time it was discovered
R136a1 is the most luminous star known to humankind.
I believe that it forms meaningful sentence.
