Answer: (B)

White or grayish-yellow patches on someone's skin are often indicative of frostbite, which occurs when skin and underlying tissues freeze due to exposure to extreme cold. In frostbite, the affected areas may appear pale, waxy, or grayish due to the loss of blood flow and the freezing of the tissue. This is a serious condition that can lead to permanent damage if not treated promptly.

Understanding the context of frostbite is essential for recognizing the condition and providing appropriate first aid. Signs of frostbite typically include cold and numb skin, pale or grayish skin, and blisters in more severe cases. Immediate action, such as gradual rewarming of the affected areas and avoiding direct heat, is crucial in managing frostbite to prevent further injury.
