6998 A. B. C. D. E.

Alright, let's try to reason this out.

We are given: 6998 and options A through E, but the options are missing here, so I will assume this is a numeric sequence or puzzle style question and that 6998 is the final term in a sequence based on some operation or the problem states: 6998 → something.

From common pattern questions:

Sometimes 6998 could be the result of some operation like multiplication, addition, or concatenation. Or possibly it's part of a number sequence and we need to choose the next term from options A, B, C, D, E.

But since I can't see the options, let's think:

Maybe:
6998
looks like "6" "9" "9" "8" digits. Could be:
6 = 3×2
9 = 3×3
9 = 3×3
8 = 4×2

Another possibility:
6998 could be: 6+9=15, 9+9=18, 9+8=17, not obvious.

Or maybe:
6998 in reverse is 8996 — sometimes in these problems you reverse digits.

Or maybe:
6998 → 6×9×9×8 = 3888 — if that’s operation.

But most likely:
6998 is the next term in a sequence where each term is derived from previous one by an operation like “multiply digits then add something” or “replace digits with their position in alphabet” — but it's all digits.

Sometimes it's:
Take number, double it → 13996 — but that’s too large.

Given no context, but if I recall some puzzles:

6998 could be part of a sequence where:
7000 → 6998 (decrease by 2) or 6998 → next? maybe 6996 (decrease by 2), but options not given.

Or:
6998 = 7,000 – 2, so next could be 7000? No, that’s increase.

If it were “6998” as the end of a sequence: 6996, 6998, __ could be 7000 if step +2.

Given typical pattern test choices, likely option A = 7000, B = 6999, C = 6997, D = 6996, E = 7002, the next one in pattern might be 7000 if step is +2 or 6999 if step +1?

But without seeing options, can’t decide.

From some known test problems, 6998 sometimes is the term where digits add up to 32 (6+9+9+8 = 32) and next one adds up to 33 if pattern is increasing sum by 1.

Let’s check:
6+9+9+8=32.
Digits of 6999 = 6+9+9+9=33.
So if options: 6999 is there, and increasing digit sum by 1 is the pattern, answer = 6999.

But since 6998 is odd? no it's even.

However, the more common trick is:
Take 6998, reverse: 8996, subtract 6998: 1998 — maybe that’s the key. Or: 6998 + 1998 = 8996?

But I'll guess:
If options are arithmetic, next maybe 6999.

---

But given the problem as stated, the only plausible “next” from 6998 in most puzzles is:
Either 6999 (if increasing by 1) or 7000 (if rounding to nearest thousand), but since they give A–E, likely it’s a digit sum pattern: 6998 sum digits 32, 6999 sum 33.

So:

$$\boxed{B}$$

(Assuming B = 6999 in the actual options.)
