The correct selection aligns with the building code requirements for egress windows and emergency escape openings. According to these regulations, an emergency escape and rescue opening must provide sufficient size for occupants to exit in case of an emergency and for rescue personnel to enter. The minimum dimensions typically required are a net clear opening height of at least 24 inches and a width of at least 20 inches.

This size ensures that individuals, including those potentially in distress or using mobility aids, can swiftly and safely escape a building in emergencies such as fires, while also allowing emergency responders to access the building if necessary. The specific dimensions of 24 inches in height and 20 inches in width meet the standard criteria, effectively balancing safety and practicality in construction design.

The other choices do not meet the established minimum height and width requirements, rendering them unsuitable for meeting safety and accessibility standards for emergency egress.
