• B. TWS
• C. ZYS
• D. UWS

Answer 1

Answer:

B. TWS

Let’s write the series:

DGC, HKG, LOK, PSO, ?

Check each position separately.

1st letters:

D → H → L → P → ?

• D (4), H (8), L (12), P (16)

• Pattern: +4 each time

So next:
P (16) + 4 = 20 → T

2nd letters:

G → K → O → S → ?

• G (7), K (11), O (15), S (19)

• Pattern: +4 each time

So next:
S (19) + 4 = 23 → W

3rd letters:

C → G → K → O → ?

• C (3), G (7), K (11), O (15)

• Pattern: +4 each time

So next:
O (15) + 4 = 19 → S

Final term:

T W S

Final Answer: TWS
