Given below are some adaptations shown by animals.
(i) Padded feet
(ii) Thick fur on the body
(iii) Can drink large quantities of water at a time
(iv) Nostrils with flaps
(v) Aestivation
(vi) Long eyelashes
Which of these adaptations are not found in polar bear?

Options

A. (i), (ii), (iii) and (v) only
B. (iii), (iv), (v) and (vi) only
C. (ii), (iii), (iv) and (vi) only
D. (i) and (ii) only

Explanation

To determine which adaptations are not found in polar bears, we will analyze each adaptation listed in the question:

1. **Padded feet**: Polar bears have padded feet that help them walk on ice and snow without slipping. This adaptation is present in polar bears.

2. **Thick fur on the body**: Polar bears have a thick layer of fur that insulates them against the cold temperatures of their Arctic habitat. This adaptation is also present in polar bears.

3. **Can drink large quantities of water at a time**: While polar bears can drink water, they primarily obtain moisture from the seals they eat, and they do not have a specific adaptation for drinking large quantities of water at once. This adaptation is not typically associated with polar bears.

4. **Nostrils with flaps**: Polar bears have nostrils that can close to keep out cold air and water, which is an adaptation to their environment. This adaptation is present in polar bears.

5. **Aestivation**: Aestivation refers to a state of dormancy or inactivity during hot or dry periods, which is not a behavior or adaptation seen in polar bears. This adaptation is not found in polar bears.

6. **Long eyelashes**: Polar bears do not have particularly long eyelashes as a specific adaptation. This adaptation is not commonly associated with polar bears.

Now, summarizing the adaptations not found in polar bears:
- Can drink large quantities of water at a time
- Aestivation
- Long eyelashes

Thus, the adaptations that are not found in polar bears are the third, fifth, and sixth adaptations listed.

**Final Answer**: The adaptations not found in polar bears are:
- Can drink large quantities of water at a time
- Aestivation
- Long eyelashes
