Final answer:
The question requires finding the quotient of given numbers, but the reference information doesn't provide clear division pairs to perform the calculation. Therefore, a correct quotient cannot be provided without additional context.
Step-by-step explanation:
The question asks to find the quotient of two sets of numbers: 6,728 and 18,931, and then choose the correct answer between options a) 274, b) 1,482, c) 328, d) 9,465. To find the quotient, you need to perform division.
However, based on the provided reference information, there isn't enough context to accurately determine which sets of numbers should be divided to obtain the quotient. Therefore, without additional information or clarity on which specific numbers need to be divided, a correct quotient cannot be provided. Quotients should be calculated by dividing the dividend (the number being divided) by the divisor (the number you are dividing by) using proper methods of division.
