Developmental psychology sorts parenting styles along two dimensions: how emotionally warm and responsive a parent is, and how much structure or demand they place on the child.
Parents who score low on warmth, offering little emotional support, but who still take care of the child's basic physical needs, fall into what's called the Neglectful or uninvolved category, distinct from Authoritative (warm and demanding), Permissive (warm but undemanding), and Democratic parenting styles.
That combination of low warmth with basic needs still being met is exactly what "Neglectful" describes, so it is the answer.
