The lap belt should be worn:

Answer: C — By pregnant women below the abdomen and the shoulder belt above the belly.

The lap belt should be worn by pregnant women below the abdomen and the shoulder belt should be worn above the belly. This is because the lap belt should be positioned low across the hips and pelvic bones to help distribute any potential impact evenly and prevent injury to the unborn baby. It is not recommended for the lap belt to touch the top of the thighs, as this could cause harm to the pelvic region in an accident. It is also not necessary for the lap belt to be worn at the abdomen for extra comfort; safety should be the primary concern while wearing a seat belt.
