Select the set in which the numbers are related in the same way as the numbers of the following sets.

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g., 13 - Operations on 13 such as adding/deleting/multiplying, etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

(676, 553),

(784, 661)

Given: (676, 553), (784, 661)

Logic: Subtract 123 from the first number to get the second number.

(676, 553) $$\rightarrow$$ 676 - 123 = 553

(784, 661) $$\rightarrow$$ 784 - 123 = 661

Explanation:​

(a) (547, 424) $$\rightarrow$$ 547 - 123 = 424​

(b) (421, 301) $$\rightarrow$$ 421 - 123 = 298 $$\neq$$ 301​

(c) (691, 581) $$\rightarrow$$ 691 - 123 = 568 $$\neq$$ 581​

(d) (752, 628) $$\rightarrow$$ 752 - 123 = 629 $$\neq$$ 628

So, only the option (a) follows the same logic.

Thus, the correct answer is option (a).
