What are UVA rays primarily associated with?

  1. Vitamin D synthesis

  2. Immediate tanning effect

  3. Aging

  4. Sunburn

The correct answer is: Aging

UVA rays are primarily associated with aging because they penetrate deep into the dermis of the skin, damaging collagen fibers and causing premature aging. While UVA rays can contribute to suntan and some vitamin D synthesis, they are not the primary factor for these effects. UVB rays are responsible for sunburn, not UVA rays.
