Step 1 : Understanding the Question:
This question contains an Assertion (A) and a Reason (R) regarding the literary definition, subject matter, and stylistic conventions of an epic poem. We need to evaluate the validity of both claims.
Step 2 : Key Formulas and Approach:
The conceptual approach involves defining the genre characteristics of the classical epic. We evaluate whether the epic uses a comic or serious subject, and if its style is formal or informal, and then use these parameters to judge the correctness of the assertion and reason.
Step 3: Detailed Explanation:
$\bullet$ An epic is historically defined as a grand, long narrative poem that traces the heroic exploits of legendary characters or covers cosmic battles of great cultural significance.
$\bullet$ Assertion (A) states that an epic is a long verse narrative on a comic subject, told in an informal style. This is incorrect; this description contradicts the primary requirements of the traditional epic genre. A comic narrative mimicking epic conventions is known as a mock-epic.
$\bullet$ Reason (R) states that an epic is a long verse narrative on a serious subject, told in a formal and elevated style. This is correct and aligns perfectly with classical models like Homer's Iliad or John Milton's Paradise Lost.
$\bullet$ Since the assertion is entirely incorrect while the reason is a structurally and historically correct definition of the epic, we conclude that (A) is false and (R) is true.
Step 4 : Final Answer:
Therefore, (A) is not correct but (R) is correct, pointing to option (D) as the correct choice.
The correct option is (D) (A) is not correct but (R) is correct.
