Don’t know but hope you have a good day
Answer:
The noun the underlined participle modifies is:
b. aspects.
Explanation:
In the sentence we are analyzing here, there is a present participle, "troubling". A present participle is formed by adding -ing to a verb stem (interesting, caring, loving, etc.). Present and past participles can function as adjectives, modifying nouns or pronouns in a sentence. That is precisely the case here, where "troubling" is modifying the noun "aspects", attributing a quality to it. For that reason, we can choose letter B as the best option.
I think what it means is that you have to know your life and what's going on around you. ( I think I'm wrong) just guessing
