• A. 2
• B. 3
• C. 4
• D. 6

Answer: (C)

For a building with an occupancy classification of Educational (E), which is sprinklered, and constructed with Type IIA materials, the North Carolina Building Code sets specific criteria regarding the maximum number of stories allowed. In the case of Educational occupancies, the code recognizes that certain conditions, such as being fully sprinklered and the type of construction used, can allow for a greater number of stories compared to non-sprinklered structures or those of a different construction type.

Type IIA construction typically offers a higher degree of fire resistance and can support more stories in educational facilities. When fully sprinklered, this construction type is allowed a maximum of four stories. Factors such as life safety, access for emergency services, and fire-resistance ratings of materials play a significant role in determining these limits within the code.

In this context, four stories for a Type IIA, sprinklered Educational building aligns with the intent of building safety while providing enough space for educational activities, making it a suitable and code-compliant choice.
