A, because its thick fur is designed to keep it warm, it would over heat and unfortunatly die
A because the bear is being brought to a new strange environment it doesn't know and it can't adapt to it so therefore it couldn't survive in it
Polar bears are specifically adapted for cold climates with thick fur and blubber, making it impossible for them to survive in the heat of tropical Singapore. They cannot regulate their body temperature effectively in such warmth, leading to heat stress. Hence, the correct answer is A. Tolerance only for cold climates.
