The correct option is "Only two" because statements 1, 2, and 3 accurately describe the Janani Suraksha Yojana (JSY), which is indeed a scheme initiated by the government to ensure safe motherhood, reduce maternal and neonatal mortality, and promote institutional deliveries, particularly among underprivileged women. However, statement 4 is incorrect; while the JSY does focus on the health of mothers and newborns, it does not explicitly include provisions for public health facilities for infants up to one year of age, as its main focus remains on maternal health and safe deliveries. Hence, only statements 2 and 3 are wholly correct in this context.
