The correct answer is C. Associated with premature labor.

The figure illustrates polymorphic eruption of pregnancy (PUPPP) with erythematous papules within striae, sparing the umbilicus. There is no associated maternal or fetal risk.

All of the remaining choices are true. It typically occurs during the third trimester or immediately postpartum, and resolves within a few weeks after delivery. It generally does not recur. There is an increased risk in primigravadas, with maternal obesity, and in twin gestations.
