Final answer:
The 'F' and 'T' ratings, referring to fire and temperature ratings of materials, are tested in accordance with either ASTM E119 or ASTM E 814 standards, or UL 263 or UL 1479 standards. These standards are set for building construction and materials testing, and fire-stop devices respectively.
Explanation:
'F' and 'T' ratings refer to fire and temperature ratings for construction materials. These ratings are determined through tests in accordance with certain standards. In your query, options B) 'ASTM E119 or ASTM E 814' and C) 'UL 263 or UL 1479' are applicable. The former pertains to Standard Test Methods for Fire Tests of Building Construction and Materials, whilst the latter corresponds to Fire-stop devices. ANSI, or the American National Standards Institute, is not mentioned in this specific context, hence why 'A' is not the correct option.
