Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(
Note:
Operations must be performed on whole numbers, without breaking them into their component digits. Take 13 for example – operations on 13, such as addition/subtraction/multiplication by 13, etc., can be performed. Breaking 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Correct answer
7 - 63
Why this answer is correct
The logic followed here is:
Logic: (1st number × 9) = 2nd number.
Now,
For, 1 : 9
⇒ (1 × 9) = 9.
For, 5 : 45
⇒ (5 × 9) = 45.
Similarly, for 7 : 63
⇒ (7 × 9) = 63.
Hence, the correct answer is "Option 1".
