In D, 'it' can refer to adolescence as well as book. Hence I went for E, why is E wrong ? and 'it' in D ?
Hello
Dhwanii,
We hope this finds you well.
To answer your query, Option E is incorrect because the pronoun "one" lacks a logical referent.
Further, Option D does not actually suffer from pronoun ambiguity, since logically "it" can only refer to "adolescence"; please remember, the error of pronoun ambiguity does not apply if only one noun can take the place of the pronoun to convey a logical meaning.
To understand the concept of "Exceptions to Pronoun Ambiguity" on GMAT, you may want to watch the following video (~2 minutes):
We hope this helps.
All the best!
