Which category penetrates to 10 millimeters of skin tissue?

Explanation:
Penetration depth depends on wavelength. Luminous infrared radiation corresponds to near-infrared wavelengths that can travel deeper into tissue, reaching deeper layers of skin and subcutaneous tissue—on the order of about a centimeter in some conditions. Nonluminous infrared radiation, which is the far infrared range, is mostly absorbed by surface tissues and does not reach as deep. Because 10 millimeters is a deeper target, the category that can reach that depth is luminous infrared radiation. This makes it the best answer.
