Rationale: Vaccination is the most effective method for preventing the spread of infectious diseases as it helps in developing immunity against specific pathogens, reducing the likelihood of infection and transmission within a population. Antibiotics are used to treat infections, not prevent their spread. Quarantine limits the contact of infected individuals but does not provide long-term prevention. Nutritional supplementation can support overall health but is not a primary method for preventing infectious diseases.

Correct Answer: B

Rationale: Breastfeeding provides passive immunity to the infant by transferring antibodies from the mother to protect the infant from infections and illnesses. This is one of the key benefits of breastfeeding, as it helps boost the baby's immune system during the early stages of life.

Rationale: A sunken fontanelle is a common sign of dehydration in infants. The fontanelle is the soft spot on an infant's head where the skull bones have not yet fused.

Rationale: Antenatal care plays a crucial role in the early detection and management of pregnancy complications, allowing healthcare providers to intervene promptly and improve outcomes for both the mother and the baby. Monitoring for potential issues during antenatal care visits can help identify problems such as gestational hypertension, gestational diabetes, or fetal growth restrictions early on, enabling timely interventions to prevent complications.

Correct Answer: B

Rationale: Children aged 1-4 years are most vulnerable to protein-energy malnutrition (PEM) due to their rapid growth and development, increased nutritional requirements, and sometimes inadequate diets. This age group is particularly susceptible to malnutrition if they do not receive adequate protein and energy-rich foods to support their growth and development.
