Possible Series Patterns:
To find the missing term in the given series, let's analyze the patterns present in the series:

1. Alphabetical Pattern:
The given series consists of alphabets arranged in a specific order. Each term in the series represents a group of four consecutive letters from the English alphabet. The first letter of each term in the series is in increasing order.

2. Incremental Numeric Pattern:
The second letter of each term in the series is incremented by 3 compared to the previous term.

3. Alphabetic Grouping Pattern:
The third and fourth letters of each term in the series follow a specific pattern. They are grouped in pairs, where the first letter of the pair is in increasing order and the second letter is in decreasing order.

Identifying the Missing Term:
Analyzing the given series based on the above patterns, we can determine the missing term as follows:

The first term of the given series is BCFG, which represents the group of four consecutive letters B, C, D, and E. The second term is JKNO, which represents the group of four consecutive letters J, K, L, and M. The third term is RSVW, representing the group of four consecutive letters R, S, T, and U.

Based on the alphabetical pattern, the missing term should represent the group of four consecutive letters starting from Z. Hence, the missing term should start with Z.

Based on the incremental numeric pattern, the missing term should have the second letter incremented by 3 compared to the previous term. The second letter in the third term is V, so the missing term should have the second letter as V + 3 = Y.

Based on the alphabetic grouping pattern, the missing term should have the third and fourth letters such that they form a pair with the first letter increasing and the second letter decreasing. The third and fourth letters in the third term are S and W, respectively. So, the missing term should have the third and fourth letters as T and X, forming the pair ST and WX.

Hence, the missing term in the given series is ZTUX, which corresponds to option A.
