Explanation:

Here’s the thing. Let’s break down how each coding scheme works so we can match it to "SENSE" ? "DRMDR".

- Scheme (a): BREAD ? EADRB

- This just shifts every letter in "BREAD" to the left by two: B (1) ? E (5), R (2) ? A (1), E (3) ? D (4), etc. But if we try this on "SENSE," we get "NSESE," which clearly doesn’t match "DRMDR."

- Scheme (b): BREAD ? CSFBE

- Here, every letter is just shifted one forward in the alphabet:

- B?C, R?S, E?F, A?B, D?E

- "SENSE" would turn into "TFOUF," not "DRMDR." Not a fit.

- Scheme (c): BREAD ? CZDQA

- Let’s check the logic—maybe applying a reverse alphabet or some pattern? Try S (19th letter) ? D (4th letter)? That looks like positions are being reflected: A?Z, B?Y, etc. Let's confirm:

- B (2) ? C (3rd letter)

- R (18) ? Z (26th letter)

- E (5) ? D (4th)

- A (1) ? Q (17th)

- D (4) ? A (1st)

- Not a direct reverse. So this doesn’t fit.

- Scheme (d): BREAD ? HEIVF

- Hard to see a direct pattern, but let's try a basic shift:

- B (2) ? H (8): shift of +6

- R (18) ? E (5): shift of -13 (no uniform pattern)

- It’s not a simple shift, so let’s move on.

Now, let's try matching the actual code for "SENSE":

- S ? D

- E ? R

- N ? M

- S ? D

- E ? R

Looks like "S" becomes "D," "E" becomes "R." Is this reverse alphabetical order, or another set mapping? If we break down "BREAD" into "DRMDR" by mapping each letter to its pair:

- B (2nd) used for D (4th), R (18th) used for R (18th), E (5th) used for M (13th), etc.

But the pattern is pointing to:

- A = Z (mirror)

- B = Y

- C = X

- D = W

- E = V

- ... etc. So let's try matching with this.

S (19th from A) ? D (4th from A)—it's reversed!

So, S (19th from start) from end is D (4th).

E (5th from A) from end is V (22nd), but in code it's R.

Wait, but in "EADRB," is this used? No.

Look: None of the schemes actually use this pattern for "DRMDR," but let's check one by one:

Let's see if EADRB (option 1) for "SENSE" could give "DRMDR." "SENSE" mapped to "DRMDR" doesn't match up with what option 1 ("EADRB") does for "BREAD."

If we test CSFBE (“B” becomes “C,” etc.) for "SENSE"—"TFOUF"—not a match.

CZDAQ tries to just re-map by a weird pattern that doesn’t match.

HEIVF—"N" isn’t used.

All things considered, none of the coding schemes given seem to match "DRMDR."

So, your answer: option 1 (E A D R B) is probably not correct.

And here’s why: the actual code for "SENSE" ("DRMDR") doesn’t follow the EADRB shifting scheme. This question is a bit tricky, but based on the mapping, none of the options fit perfectly. If I had to pick, I’d look closer at pattern c ("C Z D Q A"), because of the changing first letters, but it doesn't directly fit either. Still, option 1 is definitely not correct for the "DRMDR" pattern.
