Match List-I with List-II:

$$\begin{gathered} \mathrm{List-I} \\ \mathrm{ Meanings} \end{gathered}$$	$$\begin{gathered} \mathrm{List-II} \\ \mathrm{ Terms} \end{gathered}$$
$\left(A\right)\text{When descent is traced through the mother}$	$\left(I\right)\text{Adi-Parvan}$
$\left(B\right)\text{Barbarians or outsiders of the Brahmanical order}$	$\left(\mathrm{II}\right)\text{Endogamy}$
$\left(C\right)\text{The first section of Mahabharata}$	$\left(\mathrm{III}\right)\text{Matriliny}$
$\left(D\right)\text{Marriage within a kin group, caste, or a group living in the same locality}$	$\left(\mathrm{IV}\right)\text{Mlecchhas}$

Choose the correct answer from the options given below:

The correct answer is (A)- (III), (B)- (IV), (C)- (I), (D)- (II).

Let us break down each term from List-II and match it with its correct meaning from List-I step-by-step:

1. (A) matches with (III):
"When descent is traced through the mother" refers to Matriliny.
In a matrilineal system, ancestral descent, lineage, and inheritance of property are traced through female ancestors (the mother's line), rather than the father's (patrilineal) line.

2. (B) matches with (IV):
"Barbarians or outsiders of the Brahmanical order" refers to Mlecchhas.
In ancient Sanskrit and Brahmanical texts, the term Mlecchha was used to describe people who did not conform to the norms of the Brahmanical social order, spoke non-Sanskrit languages, or belonged to foreign lands.

3. (C) matches with (I):
"The first section of Mahabharata" is called the Adi-Parvan.
The epic Mahabharata is divided into 18 books or sections, known as Parvans. The first book, which introduces the background, origin of the dynasties, and the early lives of the Pandavas and Kauravas, is called the Adi Parva (where Adi means first or beginning).

4. (D) matches with (II):
"Marriage within a kin group, caste, or a group living in the same locality" is known as Endogamy.
Endogamy is a social rule or practice where individuals are required or expected to marry within their own specific social group, such as a caste, clan, class, or geographical community.

By putting these individual matches together, we get:
(A) → (III)
(B) → (IV)
(C) → (I)
(D) → (II)

This corresponds exactly to the correct option.
