Step 1: Convert to positions:
l=12, g=7, z=26;
f=6, a=1, t=20;
v=22, q=17, j=10;
d=4, y=25, p=16.
Step 2: Check differences (cyclic if needed):
l$\rightarrow$g: $-5$, g$\rightarrow$z: $+19$;
f$\rightarrow$a: $-5$, a$\rightarrow$t: $+19$;
v$\rightarrow$q: $-5$, q$\rightarrow$j: $-7$.
Step 3: First two groups follow pattern ($-5$, then large forward jump). Third group breaks consistency, and (d, y, p) does not follow similar structured differences.
Step 4: Hence, (d y p) is the odd one out $\Rightarrow$ option (C).
