Final answer:
Low maternal sensitivity when infants are 15 and 24 months old has been linked to a higher risk of obesity in adolescence. Thus, the option B is the correct answer.
Step-by-step explanation:
Low maternal sensitivity when infants are 15 and 24 months old has been linked to higher risk of obesity in adolescence. This means that when mothers are less responsive to their infants' needs during these ages, it can contribute to a higher likelihood of obesity when the child becomes an adolescent. It is important for mothers to provide sensitive and nurturing care during these critical stages of development to promote healthy outcomes.
