https://www.nytimes.com/1997/01/23/us/researchers-get-first-detailed-look-at-magnetic-cloud-from-sun.htmlAn international group of space scientists said that on Jan. 6 the Sun ejected a pocket of mass from its corona that developed into a giant, tube-shaped magnetic bubble 30 million miles in diameter that hit Earth almost four days later. The
expanding cloud of energized particles triggered a large storm in the magnetic field, or magnetosphere, surrounding the planet. The storm
brightened the Northern Lights and possibly
knocked out a communications satellite.
Hi
GMATNinja VeritasKarishmaPlease help me with C and D. Many posts indicate that as per the intended meaning "Scientists were monitoring cloud and not storm", but isn't it logical that they could monitor the path of the storm as well?. Given I didn't get what scientists were monitoring I was able to come down to option C and D.
Although there is no error present in option C, I didn't see any error in D as well. Here is my analysis of option D, your response and time will be much appreciated.

We have "A large storm in the magnetic field that surrounds Earth,
[modifier, modifying large storm], brightened the Northern Lights and it possibly knocked". Breaking down it further and removing the modifier for a moment the sentence is joined by "and" and looks like below
1. A large storm in the magnetic field that surrounds Earth brightened the Northern Lights - In this IC we have "A large storm as subject and brightened as the verb"
2. It possible knocked out a communication satellite - "It" is the subject of the second IC joined by "and" and knocked is the verb
Now a lot of posts eliminate option D because of ambiguity of pronoun "it", but
GMATNinja in your video on "Next-level Gmat pronoun", by using the
example you, mentioned that "when we have two IC then subject of second IC
can refer back to the subject of first IC unambiguously. So based on same logic isn't "it" referring back to a large storm unambiguously?
