D. R,S

Explanation

To solve the given series B, C, F, E, J, G, N, I, ?, ?, we need to identify the pattern in the sequence.

### Step-by-Step Solution:

1. **Identify the first pattern (odd positions):**
- The first term is B.
- The third term is F.
- The fifth term is J.
- The seventh term is N.

To find the next term in this pattern:
- B (2nd letter) → F (6th letter) → J (10th letter) → N (14th letter).
- The pattern here is that we are skipping 1 letter after B (C), skipping 1 letter after F (G, H), skipping 1 letter after J (K, L), and skipping 1 letter after N (O, P, Q).
- The next letter after N (14) will be O (15), P (16), Q (17) → R (18).

So, the next term in this pattern is **R**.

2. **Identify the second pattern (even positions):**
- The second term is C.
- The fourth term is E.
- The sixth term is G.
- The eighth term is I.

To find the next term in this pattern:
- C (3rd letter) → E (5th letter) → G (7th letter) → I (9th letter).
- The pattern here is that we are skipping 1 letter after C (D), skipping 1 letter after E (F), skipping 1 letter after G (H).
- The next letter after I (9) will be J (10), K (11) → K (11).

So, the next term in this pattern is **K**.

### Final Answer:
The missing terms in the series are **R** and **K**.
