Final answer:
The correct set of conversion factors between the various yard-based units, given the conversion of 3 feet to 1 yard, is option b: 1 (Ayd/Cyd), 36 (ft/Ayd), and 36 (B/C).
Step-by-step explanation:
The question appears to be asking for a unit conversion between different units of measurement, specifically converting to yards (yd) from other units, and then requiring a matching of conversion factors.
From the provided options, we have to determine the correct conversion factors between yards, some unspecified unit 'A', and some unspecified unit 'C'. We know from measurement conventions that 1 yard is equivalent to 3 feet, which helps us to find the correct conversion factors.
Option b is the correct set of conversion factors based on the provided information. This is because 1 yard can be denoted as 1 yd, which directly corresponds with the provided conversion where 3 feet equal 1 yard. Therefore, for the sequence of conversions given by Ayd = ___Cyd, B ft = ___Ayd, B = ___C, the factors would be: 1 (Ayd/Cyd), 36 (ft/Ayd), and 36 (B/C).
