Verified step by step guidance

Understand that the problem is asking about the physiological changes in a Himalayan rabbit due to cold weather.

Recall that Himalayan rabbits have a unique genetic trait where their fur color changes in response to temperature.

Recognize that in colder temperatures, the extremities of the rabbit (ears, nose, paws, and tail) develop darker fur.

This change in fur color is due to a temperature-sensitive enzyme called tyrosinase, which is active in cooler temperatures and leads to the production of melanin, causing the fur to darken.

Conclude that the aspect of a Himalayan rabbit that changes due to cold weather is its fur color, as the other options (body size, dietary habits, heart rate) are not directly affected by temperature in the same way.
