The structure that connects the pulmonary artery to the aorta in a fetus is called the ductus arteriosus, which allows blood to bypass the lungs and go directly to the body. The other structures listed (umbilical vein, umbilical artery, and ductus venosus) are involved in fetal circulation but not in connecting the pulmonary artery to the aorta.
