Find the odd one out.

The correct option is EDA.

To find the odd one out, we can analyze the positions of the letters in the English alphabet for each option and find the differences between consecutive letters:

1. ZYW:
The alphabetical positions are Z = 26, Y = 25, and W = 23.
The difference between the first and second letters is:
$26-25=1$
The difference between the second and third letters is:
$25-23=2$

2. MLJ:
The alphabetical positions are M = 13, L = 12, and J = 10.
The difference between the first and second letters is:
$13-12=1$
The difference between the second and third letters is:
$12-10=2$

3. SRP:
The alphabetical positions are S = 19, R = 18, and P = 16.
The difference between the first and second letters is:
$19-18=1$
The difference between the second and third letters is:
$18-16=2$

4. EDA:
The alphabetical positions are E = 5, D = 4, and A = 1.
The difference between the first and second letters is:
$5-4=1$
The difference between the second and third letters is:
$4-1=3$

We observe that for ZYW, MLJ, and SRP, the pattern of differences is 1 and 2 (moving backwards by 1 and then 2 positions). However, for EDA, the pattern of differences is 1 and 3 (moving backwards by 1 and then 3 positions). Therefore, EDA is the odd one out.
