The Moro reflex is most likely to be produced when:
A) someone lightly stokes the baby's cheek.
B) the baby loses support of his or her head.
C) the baby smells his mother's breast milk.
D) the baby's palm is pressed.
Answer: B
Rationale: The Moro reflex, also known as the "startle" reflex, occurs when infants lose support of their head. Infants grimace and reach their arms outward and then inward in a hugging motion. This may be a protective reflex that allows the infant to hold on to the mother when support is suddenly lost.
