Context Extrinsic aging, also known as environmental aging, is caused by external factors such as sun exposure, pollution, and lifestyle choices. The other options, including lifestyle choices, genetics, and diet, are all factors that can contribute to overall health and skin appearance, but they are not the primary cause of extrinsic aging. While lifestyle choices and diet can impact skin aging, they are not the number one factor. Additionally, while genetics can determine skin type and natural aging process, it is not the main cause of extrinsic aging. Therefore, the correct answer is C: Amount of sun exposure. Overexposure to the sun's UV rays is the main cause of extrinsic aging, including wrinkles, dark spots, and loss of elasticity. Protecting your skin from the sun's harmful rays is essential in preventing and slowing down extrinsic aging.
