Final answer:

The standard thickness for a solid wood door or solid or honeycomb-core steel door between a garage and residence, for fire-resistant qualifications, is typically 1 and 3/8 inches. The closest answer from the options given is 1 inch.

Step-by-step explanation:

The question relates to building code requirements, specifically the thickness of doors between a garage and residence in a home construction context.

These types of doors are required to have a certain level of fire resistance to prevent the spread of flames and gases in case of a fire in the garage. The standard door thickness that meets these requirements is 1 and 3/8 inches. However, since none of the mentioned options align exactly with this standard, it seems there might be a discrepancy in the question provided.

Generally, most building codes will require a 1 3/8-inch thick solid wood door, or a solid or honeycomb-core steel door that meets the fire-resistant qualifications. Therefore, from the options provided, the closest would be 1 inch thickness, although it's not the precise standard.

According to building codes, other openings between the garage and residence should be equipped with solid wood doors or solid or honeycomb-core steel doors that are not less than 1.75 inches thick. This thickness is necessary for safety and to provide a barrier against fire and fumes.
