GMATNinjaI have a doubt Sir.
In option C, which is the correct answer, How present participle "thereby improving stability in flight and resulting in longer throws" making sense with the subject of preceding clause?
Though it is clear that it is acting as an adverbial modifier, as per my knowledge it should make sense with subject also.
For Ex: Sam lined the discus with lead, thereby improving the stability.
In above sentence "thereby improving the stability" is acting as an adverbial modifier, and it is also making sense with subject of preceding clause i.e Sam action results to improvement.
Please help.

In this example, it's not the kids themselves that are giving Tim a moment of peace. It's the fact that they're sleeping.
Similarly, it's not the discus itself that improves stability. It's the fact that the discus
lined with lead.
In both cases, the "-ing" modifier modifies the action performed by the subject, not the subject itself.
What is that action in choice (C)? BEING lined with lead. What "performs" that action? The discus. So the "-ing" modifier makes sense with the verb and its subject.
