The correct answer is D. Pemphigus gestationis.

Pemphigoid gestationis (PG) is an autoimmune blistering disorder that typically presents with pruritic urticarial plaques and papules around the umbilicus, which can later generalize and form blisters. It often flares around the time of delivery and can recur in subsequent pregnancies. The diagnosis is supported by the presence of urticarial plaques involving the umbilicus and the history of recurrence and flare around delivery.

Atopic eruption of pregnancy (A) presents with eczematous lesions on the face, neck, and flexural areas, not typically involving the umbilicus. It is the most common pruritic disorder of pregnancy but does not match the described presentation. Impetigo herpetiformis (B) is a form of pustular psoriasis that presents with pustules rather than urticarial plaques. Polymorphic eruption of pregnancy (C) typically spares the umbilicus and is more common in primigravidas. It usually resolves shortly after delivery and does not typically flare around delivery. Nummular dermatitis (E) presents with coin-shaped eczematous plaques, which are not described in the clinical scenario. It is not typically associated with pregnancy.
