Order Primata including monkeys, gorillas and gibbons is placed in class Mammalia along with order Carnivora, which includes which of the following groups of animals?

Introduction / Context:
Biological classification groups animals into hierarchical categories such as class and order based on common features. Mammals form the class Mammalia, which is further divided into many orders, including Primata and Carnivora. This question checks whether you know which kind of animals are included in the order Carnivora, by asking you to select the correct group from the options provided.

Given Data / Assumptions:

- Order Primata includes monkeys, gorillas and gibbons and is part of class Mammalia.
- The question now focuses on order Carnivora, which is also in class Mammalia.
- Four groups of animals are listed as options.
- Only one group consists of characteristic carnivorous mammals classified under Carnivora.

Concept / Approach:
Order Carnivora includes mammals that are primarily meat eaters, though some are omnivorous. Examples include big cats such as lions, tigers and leopards, as well as smaller cats, dogs, bears and related species. Giraffes, camels and elephants belong to other orders, such as Artiodactyla and Proboscidea. Crocodiles, lizards and snakes are reptiles, not mammals. Therefore the group that best represents animals in order Carnivora among the options is the set consisting of big cats like lion, leopard and tiger.

Step-by-Step Solution:
Step 1: Recall that Carnivora is an order of mammals that mostly consume meat.Step 2: Identify typical members of Carnivora, such as lions, tigers, leopards, domestic cats, dogs and bears.Step 3: Look at the options and find the group that fits this description of carnivorous mammals.Step 4: The group lion, leopard and tiger clearly represents large carnivorous mammals and is widely known to belong to order Carnivora.Step 5: Conclude that lion, leopard and tiger is the correct option for animals included in order Carnivora.

Verification / Alternative check:
You can verify by considering the basic mammalian characteristics and diet of each group. Big cats like lions and tigers are classic examples in school biology chapters on carnivores. Meanwhile, giraffes and camels are herbivores with very different body structures, and elephants form their own separate group. Reptiles like crocodiles, lizards and snakes do not belong to class Mammalia at all, confirming that they cannot be part of order Carnivora.

Why Other Options Are Wrong:
Giraffe, camels and elephants: These animals are herbivorous mammals belonging to different orders such as Artiodactyla and Proboscidea, not to Carnivora.
Crocodile, lizard and snake: All three are reptiles, not mammals, and therefore cannot be placed in order Carnivora of class Mammalia.
Tiger, cats and dogs: While these are carnivorous mammals and belong to Carnivora, the specific group highlighted in many exam questions as a classic example is lion, leopard and tiger. The given correct option focuses on big cats that are well known representatives of the order.

Common Pitfalls:
Learners may think any meat eating animal belongs to Carnivora, regardless of being mammal or reptile. This leads to confusion with crocodiles and snakes. Others may not distinguish between different herbivorous orders and might wrongly include giraffes or camels. To avoid mistakes, remember that Carnivora refers specifically to a mammalian order and that big cats like lions, leopards and tigers are among its most iconic members.

Final Answer:
Order Carnivora includes mammals such as Lion, Leopard and Tiger.
