The answer is the second one: low levels of sunlight.

Explanation for each option:

1. High levels of dopamine: This is incorrect. Major depressive disorder with seasonal pattern, also known as Seasonal Affective Disorder (SAD), is not typically associated with high levels of dopamine.
2. Low levels of sunlight: This is correct. SAD is often linked to reduced exposure to sunlight during the shorter days of fall and winter, which can affect the body's internal clock and lead to symptoms of depression.
3. High levels of thyroxine: This is incorrect. Thyroxine is a hormone produced by the thyroid gland, and its high levels are not typically associated with SAD.
4. Low levels of thyroxine: This is incorrect. While thyroid function can influence mood, low levels of thyroxine are more commonly associated with hypothyroidism, not specifically with SAD.

Summary: Major depressive disorder with seasonal pattern seems to be related to low levels of sunlight.
