Answer 1

The Correct Option is B

The National Building Code of India (NBC) provides guidelines for regulating building construction activities across the country. Part 3 of the NBC deals with "Development Control Rules and General Building Requirements," and Part 4 deals with "Fire and Life Safety." In these parts, particularly concerning fire safety and occupancy types, buildings are classified based on their occupancy or use. According to the National Building Code of India (e.g., NBC 2005, NBC 2016), buildings are classified into the following 9 groups based on occupancy:
Group A: Residential Buildings (e.g., houses, apartments, dormitories)
Group B: Educational Buildings (e.g., schools, colleges)
Group C: Institutional Buildings (e.g., hospitals, nursing homes, care homes, jails)
Group D: Assembly Buildings (e.g., theaters, cinemas, assembly halls, stadiums, transport terminals)
Group E: Business Buildings (e.g., offices, banks, courts)
Group F: Mercantile Buildings (e.g., shops, stores, markets)
Group G: Industrial Buildings (e.g., factories, workshops - subdivided into G1, G2, G3 based on hazard)
Group H: Storage Buildings (e.g., warehouses, godowns, cold storages)
Group J: Hazardous Buildings (buildings for storage, handling, manufacture or processing of highly combustible, explosive, toxic, or corrosive materials) There are 9 such major occupancy classifications (A to J, excluding I which is not used to avoid confusion with number 1). Therefore, as per NBC, buildings are classified into 9 types based on their occupancy. \[ \boxed{9} \]
