The correct answer is option 'D' which states that the bear was not as strong as it could bill a cow or carry it between its two paws.

Explanation:
- Option 'A': As strong that it could bill a cow
Bears are indeed strong animals, but they are not capable of "billing" a cow. The word "bill" here seems to be a typographical error and should probably be "kill". However, even in that case, bears are not known to hunt and kill adult cows. They primarily feed on fish, berries, nuts, and occasionally smaller mammals.

- Option 'B': Carried it between his two paws
Bears are powerful creatures, but they are not capable of carrying adult cows between their two paws. Adult cows weigh significantly more than bears and are much larger in size. Bears do not have the strength or physical structure to lift and carry such large animals.

- Option 'C': Both A and B
Since both options A and B have been explained to be incorrect, option C, which combines both A and B, is also incorrect.

- Option 'D': None of these
This is the correct answer. The bear is strong, but it cannot bill a cow or carry it between its two paws. The bear's strength is sufficient for its survival and hunting smaller prey, but it is not capable of overpowering large animals like cows.

In conclusion, the bear in question is strong but not to the extent of being able to bill a cow or carry it between its two paws.

Answer:

The given question asks about the strength of a bear and provides two options: (a) as strong that it could kill a cow and (b) carrying a cow between its two paws. The correct answer is option 'D', none of these.

Explanation:

The actual strength of a bear cannot be accurately determined based on the given options. While bears are indeed strong animals, the options provided in the question exaggerate their strength.

Strength of a Bear:

Bears are known for their strength, especially when compared to many other animals. Here are some key points about the strength of bears:

1. Physical Power: Bears have strong muscles and large bodies, which allows them to perform impressive feats of strength. They are capable of running, climbing, and swimming with ease.

2. Predatory Abilities: Bears are opportunistic predators and can overpower smaller animals. They are known to hunt and kill animals such as deer, fish, and smaller mammals.

3. Foraging Strength: Bears are also adept at foraging for food. They can easily tear apart logs and dig through the ground with their powerful claws in search of insects, roots, and other food sources.

4. Display of Strength: Bears can exhibit their strength in various ways, such as standing on their hind legs, swiping with their paws, or wrestling with other bears.

5. Survival Skills: Bears have evolved to survive in different habitats and climates. Their strength plays a crucial role in their ability to find food, defend themselves, and protect their young.

Conclusion:

While bears are undoubtedly strong animals, the given options (a) and (b) in the question exaggerate their strength. It is essential to consider the natural behavior and capabilities of bears without resorting to unrealistic assumptions. Therefore, the correct answer to the question is option 'D', none of these.
