Z, X, V, T, R, ….., …..

Options

A. O, K
B. N, M
C. K, S
D. P, N

Explanation

To solve the problem, we need to identify the pattern in the given series of letters: Z, X, V, T, R, …, …

### Step 1: Identify the Pattern
The series starts with Z and moves backwards in the alphabet. We can observe the following:

- Z (1st letter)
- X (3rd letter)
- V (5th letter)
- T (7th letter)
- R (9th letter)

The pattern shows that we are skipping one letter each time.

### Step 2: Continue the Pattern
Following the established pattern, we need to find the next two letters after R:

- After R (which is the 18th letter), we skip Q (17th letter) and take P (16th letter).
- After P, we skip O (15th letter) and take N (14th letter).

### Step 3: Write the Result
Thus, the next two letters in the series are P and N.

### Final Answer
The missing letters are P and N.
