Ultrasound is the best choice to determine the number of babies in a pregnancy. It is noninvasive and provides accurate visualization of the fetus(es). The other tests listed (quadruple maternal blood test, amniocentesis, chorionic villus sampling) are not specifically designed to determine the number of fetuses and are typically used for other purposes during prenatal care.
