Correct Answer: C

Rationale: The correct answer is C: Apply a cream or lotion to the area. This is because radio-dermatitis is a common side effect of radiation therapy, causing skin irritation and dryness.

Leaving the skin alone may prolong discomfort and delay healing. Avoiding creams or lotions can worsen dryness and discomfort. Overall, applying a suitable cream or lotion is the most effective method to alleviate symptoms and support skin recovery in radio-dermatitis.
