Classification involves identifying the ___ among a group of items based on a common feature or pattern shared by the rest.

Odd one out

True or False: In classification questions, three options typically share a common pattern.

True. In most classification questions, three options share a common pattern and one option is different.

Which one does NOT follow the same pattern: WZT, KNH, RUQ, DGA?

RUQ is the odd one out.
 In WZT, KNH, and DGA, letters follow a consistent alphabetical skipping pattern, whereas RUQ does not follow the same pattern.

Example: CFI, UXA, RUX, SVZ — which one is different?

SVZ. 

All groups have letters increasing by +3 alphabetically, except SVZ, which increases by +3 then +4. Hence, SVZ is different.

BLACK – ABCKL

In BLACK – ABCKL, the letters are arranged in alphabetical order (A, B, C, K, L).
In the other pairs, the letters are rearranged but not in alphabetical order.
