A series is given, with one term missing. Choose the correct option from the given ones that will complete the series.
EDC, GHI, MLK, OPQ, UTS, ?

Let us analyze the groups of letters and their positions in the English alphabet:
1. EDC $\to$ CDE reversed (positions $5,4,3$)
2. GHI $\to$ GHI straight (positions $7,8,9$) [Gap of $1$ letter, F omitted]
3. MLK $\to$ KLM reversed (positions $13,12,11$) [Gap of $1$ letter, J omitted]
4. OPQ $\to$ OPQ straight (positions $15,16,17$) [Gap of $1$ letter, N omitted]
5. UTS $\to$ STU reversed (positions $21,20,19$) [Gap of $1$ letter, R omitted]

Following the same logic:

* Omit $1$ letter after U ($21$), which is V ($22$).
* The next $3$ letters are W ($23$), X ($24$), Y ($25$).
* The order alternates between reversed and straight: reversed $\to$ straight $\to$ reversed $\to$ straight $\to$ reversed $\to$ straight.
* Therefore, the next term in straight order is WXY.
