Blanching occurs as tissue turns white or has a lighter color as a result of inappropriate blood flow. One of the main causes of blanching is lesions produced by cold as low temperatures produce reduced blood flue and therefore, this lesion produces blanching. This has symptoms such as tingling sensation, numbness, and even issues to move the limb or part of the body that has been exposed to cold. Additionally, this lesion should be treated by using external heating; although, in severe cases, the tissue might be irreversibly affected. So, the correct answer is B. White or lighter
