Explain why D is correct?

How is D the correct answer? The question reads, "The passage suggests that daycare is at best a limited solution to the pressures associated with child-rearing for all of the following reasons EXCEPT:" A: Supported by lines 11-12, "they also need meaningful time with their parents." But the author is not suggesting that the best daycare available cannot guarantee this, the author is just stating that this is a child's need. So wouldn't this be the correct answer? B: Supported by line 7, "...workers cannot always find or afford suitable care." C: Supported by line 7, "...workers cannot always find or afford suitable care." D: Supported by lines 4-5, "children in primary school need care after school and during school vacations." So how is this the correct answer? E: Supported by lines 8-10, "Even when they obtain such care, parents must still cope with emergencies, such as illnesses, that keep children at home."
