From the given responses, find the missing letter cluster in the series.
GH, HIJ, JKL, MNOPQ,?

Correct option is A

Explanation: The given series of letter clusters follows a pattern where the number of letters increases incrementally. Let's analyze each part:
1. GH (2 letters)
2. HIJ (3 letters)
3. JKL (3 letters)
4. MNOPQ (5 letters)
The sequence follows this pattern:
· The first part has 2 letters (GH), the next has 3 letters (HIJ), the next also has 3 letters (JKL), and the fourth has 5 letters (MNOPQ). Based on this progression, we can predict that the next cluster will have 6 letters.
The letters following MNOPQ are QRSTUV, which consists of 6 letters.
Thus, the missing letter cluster is QRSTUV, making the correct answer (a).
