Assertion (A) is correct as both Toni Morrison and Adrienne Rich have indeed developed distinctive styles in literature, showcasing their unique voices and perspectives.
Reason (R) is also correct; it highlights Rich's view on feminism, where personal experiences (subjectivity) and political action intersect.
However, while (R) explains the context of Rich's work, it does not directly explain the distinctive styles of both authors. Thus, both are correct, but (R) is not the correct explanation of (A).
