If a child care facility did not hold a valid license on October 1, 1992, what is the minimum usable indoor floor space required per child to obtain regulatory approval?

The correct minimum usable indoor floor space required per child, for a child care facility that did not hold a valid license on October 1, 1992, is 35 square feet. This standard is established in order to ensure that there is enough space for children to engage in activities safely and comfortably. Adequate space contributes to a positive environment conducive to learning and development.

When regulations are set, they often revolve around promoting the well-being of children in care. The minimum space requirement is a critical aspect because it not only addresses safety considerations but also supports various aspects of child development, including socialization, play, and educational activities.

The other options, while they may represent space requirements for other contexts or licensure situations, do not reflect the requirement for facilities without a valid license prior to that date. Thus, the requirement of 35 square feet is both a regulatory measure and a best practice aimed at fostering an adequate environment for children in childcare settings.
