Match List-I with List-II: List-I Placental mammals List-II Counterpart Marsupials (A) Anteater (II) Numbat (B) Bobcat (IV) Tasmanian tiger cat (C) Lemur (I) Spotted cuscus (D) Flying squirrel (III) Flying Phalanger Choose the correct answer from the options given below:

List-I Placental mammals	List-II Counterpart Marsupials
(A) Anteater	(II) Numbat
(B) Bobcat	(IV) Tasmanian tiger cat
(C) Lemur	(I) Spotted cuscus
(D) Flying squirrel	(III) Flying Phalanger

(A) - (II), (B) - (IV), (C) - (I), (D) - (III)

(A) - (II), (B) - (I), (C) - (IV), (D) - (III)

(A) - (IV), (B) - (I), (C) - (II), (D) - (III)

(A) - (IV), (B) - (I), (C) - (III), (D) - (II)

Correct Option: (1)

To solve the problem of matching List-I (Placental mammals) with List-II (Counterpart Marsupials), we need to identify the respective pairs. Here's how the matching works: List-I Placental mammals List-II Counterpart Marsupials (A) Anteater (II) Numbat (B) Bobcat (IV) Tasmanian tiger cat (C) Lemur (I) Spotted cuscus (D) Flying squirrel (III) Flying Phalanger We will verify the correct answer by checking each pair one by one: Anteater is matched with the Numbat, a marsupial that also has a long tongue and eats termites, thus (A) - (II). Bobcat is similar to the Tasmanian tiger cat in behavior and ecological niche, hence (B) - (IV). Lemur is matched with the Spotted cuscus, both being arboreal and nocturnal, meaning (C) - (I). Flying squirrel matches with the Flying Phalanger as both can glide, resulting in (D) - (III). Therefore, the correct matching is: (A) - (II), (B) - (IV), (C) - (I), (D) - (III).
