Pattern in the Given Sequence:
The given sequence is EDCBA : ABCDE. We need to find the correct option that follows the same pattern. Let's analyze the given sequence to understand the pattern:

1. Reverse Order:
In the given sequence, the letters are in reverse order. Starting from E, each subsequent letter is alphabetically one step before the previous letter. So, the sequence can be written as:

E (5th letter) D (4th letter) C (3rd letter) B (2nd letter) A (1st letter)

2. Reverse Pattern:
The pattern in the given sequence is that the letters are in reverse order, while their positions remain the same. In other words, the first letter is at the 5th position, the second letter is at the 4th position, and so on.

Applying the Pattern:
Now, let's apply the same pattern to the options given:

a) FGHIJ: JIHGF
b) VWXYZ: ZYXWV
c) MNOPQ: QPONM
d) RSTUV: VUTSR

Among the given options, option B (VWXYZ: ZYXWV) follows the same pattern as the given sequence. The letters are in reverse order, maintaining their positions.

Therefore, the correct answer is option B) VWXYZ : ZYXWV.

Conclusion:
The pattern in the given sequence is that the letters are in reverse order, while their positions remain the same. Applying this pattern, we find that option B) VWXYZ : ZYXWV is the correct answer.
