Explanation:

To find the odd word/number/letters/number pair, we need to analyze the given options and identify any patterns or characteristics that make one option different from the others.

Let's analyze each option:

a) 5061
b) 4025
c) 7202
d) 6023

To identify the odd option, we can focus on the characteristics of each option and compare them to see if there is any pattern or rule that applies to all except one.

Analyzing the options:

a) 5061
The digits in this number are 5, 0, 6, and 1. There doesn't seem to be any specific pattern or rule that applies to this number.

b) 4025
The digits in this number are 4, 0, 2, and 5. Similarly, there doesn't seem to be any specific pattern or rule that applies to this number.

c) 7202
The digits in this number are 7, 2, 0, and 2. Again, there doesn't appear to be any specific pattern or rule that applies to this number.

d) 6023
The digits in this number are 6, 0, 2, and 3. Once again, there doesn't seem to be any specific pattern or rule that applies to this number.

Comparing the options:

After analyzing all the options, we can conclude that there is no distinct pattern or rule that applies to any of the numbers. Therefore, we need to look for any other characteristic or feature that makes one option different from the others.

In this case, the odd option is 'a) 5061' because it is the only option that does not have a repeated digit. All the other options have at least one digit that is repeated, while 'a) 5061' has all distinct digits.

Hence, the correct answer is option 'A'.
