Choose the odd word/letters/number/number pair from the given alternatives.

Let's analyze the relation between the digits of each 4-digit number. If we add the first three digits, we get the last digit or a component of it:
6260: Sum of first three digits =6+2+6=14

=0

8411: Sum of first three digits =8+4+1=13

=1

Let's look at another pattern: dividing the number into parts or summing the digits.
Sum of digits:

6+2+6+0=14

8+4+1+1=14

9+4+1+3=17

5+6+1+1=13
This does not yield a uniform rule for three options.

Let's observe the relationship between the first two digits and the last two digits:

6260: 62−60=2

8411: 84−11=73

Let's check another simple digital pattern: The sum of the first two digits equals the last two digits as a number, or sum of outer and inner digits.
Let's try: First two digits minus second two digits? No.

Let's check the sum of individual digits again:

6+2+6+0=14

8+4+1+1=14

9+4+1+3=17

5+6+1+2=14

Notice that for options A, B, and D, the sum of all digits is exactly 14:

6260: 6+2+6+0=14

8411: 8411→8+4+1+1=14

5612: 5+6+1+2=14

For option C:

9413: 9+4+1+3=17

=14

Hence, 9413 is the odd one out.
