Correct option is A
Explanation-
Option a : Lemurs are more closely related to lorises than to gibbons.
Lemurs and lorises both belong to the group called Strepsirrhines (also known as "wet-nosed primates"). Gibbons, on the other hand, belong to Haplorhines (or "dry-nosed primates"), which include monkeys, apes, and humans. So, lemurs are indeed more closely related to lorises than to gibbons.
Incorrect options -
Option b: Orangutans are closer to lorises than to gibbons.
Orangutans are great apes (Haplorhines), like gibbons. Lorises are Strepsirrhines. Orangutans are much more closely related to gibbons than to lorises.
Option c : Tarsiers are same as old world monkeys.
Tarsiers are part of Haplorhines, but they are not Old World monkeys. Old World monkeys (like baboons, macaques) belong to a different group called Catarrhines. Tarsiers are quite distinct and form their own subgroup within Haplorhines.
Option d : Humans are closer to new world monkeys than to orangutans.
Humans are much closer to orangutans (both are great apes). New World monkeys (like capuchins, marmosets) are more distantly related. Humans and orangutans share a more recent common ancestor.
Correct Answer: Option a - Lemurs are more closely related to lorises than to gibbons.
