Step 1 : Understanding the Question:
This question requires us to evaluate an Assertion (A) and a Reason (R) concerning the definitions and differences between biography, autobiography, memoir, and diaries as literary genres.
Step 2 : Key Formulas and Approach:
The approach involves defining each of these genres clearly. We compare these definitions with the assertions made in both statements to determine which of them are correct.
Step 3 : Detailed Explanation:
• A biography is a detailed account of a person's life written by someone else, while an autobiography is written by the subject themselves.
• A memoir is a sub-genre of autobiography that focuses on a specific period, theme, or series of events in the author's life, rather than providing a comprehensive chronological life story. Therefore, Assertion (A) is correct because biography and memoir are indeed different literary genres.
• However, Reason (R) is incorrect because it falsely defines biography as being "written by the subject about himself or herself" (which is actually the definition of an autobiography).
• Reason (R) also incorrectly defines a memoir as "a day-to-day record of events in one's life written for personal use" (which is the definition of a diary or journal).
• Since the Assertion is true but the Reason contains multiple definitional errors, (A) is correct but (R) is false.
Step 4 : Final Answer:
Assertion (A) is correct, but Reason (R) is not correct.
The correct option is (C) (A) is correct but (R) is not correct.
