Answer:
I should avoid prolonged sun exposure.
Step-by-step explanation:
Systemic lupus erythematous may be defined as the medical condition in which the body's immune system starts attacking the healthy body tissue. This is an autoimmune disease.
The disease affects the kidneys, brain, joints and skin. The individual should avoid the excess exposure to the ultraviolet light and the sun's light. This light might result in the increase in the disease progression and exacerbations of the disease.
Thus, the correct answer is option (b).
