Neonaticide refers to the killing of a child who is...

• A. Less than 1 week old
• B. 1 week to 1 year old
• C. More than 1 year old
• D. At birth only

Answer: (A)

The key idea here is age-based terminology for crimes against newborns. Neonaticide describes killing a newborn within the very early period after birth. In this item, the window used is less than a week old, which fits the idea of neonaticide as the newborn period right after birth rather than later infancy.

So, the best choice fits the newborn stage within the first days to the first week of life. The other options describe later stages—one week to a year is infanticide, more than a year is outside the neonatal period, and “at birth only” is a narrower definition not aligned with the given timeframe here.
