on average a parent of a four year old in the US who was not eligible for subsidies could expect to pay? for center based care

c) $10,000 - $15,000 per year

Explanation:

Given that according to a research survey, 10 percent or less in terms of child care facilities are actually approved, and at the same time center-based care can cost up to 12,000 dollars a year or more.

Hence, considering the available options, the correct answer to the question is option C which is on average a parent of a four-year-old in the US who was not eligible for subsidies could expect to pay between $10,000 to $15,000 per year.
