Explanation:

Let’s break it down:

- AQUARIUM becomes ZSREMONU. If you look at the pattern, notice this:

Each letter is moved back by one in the alphabet ('A' to 'Z', 'Q' to 'P', 'U' to 'T', etc.), so it's “reverse shifting” by one place.

- So, for HUMIDITY:

H ? G

U ? T

M ? L

I ? H

D ? C

I ? H

T ? S

Y ? X

- Shift each letter of HUMIDITY back by one spot:

H U M I D I T Y

G T L H C H S X

- Your answer (option 4: GWJMYOMG) doesn’t match that shifting pattern. The first letter should be G (from H->G), but the second letter U->T is not W, so something is off.

- Let's check the options:

Option 1: GVJMXOMG

Option 2: IWJNYOMG

Option 3: IVJNYOMH

Option 4: GWJMYOMG

- Only Option 1 starts with G (right), V (U->V is forward, not back), so the logic feels inconsistent.

But looking at the answer key pattern from AQUARIUM:

- Let's test another possible pattern:

Are they reversing the string and shifting by one?

- "AQUARIUM" reversed: MUIRAUQA

- Each letter in "MUIRAUQA" shifted +1 gives: N V J S B V R B

- That doesn’t match ZSREMONU.

- Wait. "AQUARIUM" to "ZSREMONU":

A?Z, Q?S, U?R, A?E, R?M, I?O, U?N, M?U

Let's map it:

AQUARIUM

Z S R E M O N U

If we compare letters:

A/Z: +25 (Backward, so -1)

Q/S: +2 (Forward, so +2)

U/R: -3

A/E: +4

R/M: -5

I/O: +6

U/N: -7

M/U: +8

That's a +1, -1, +2, -2, +3, -3... pattern!

Let’s do this for HUMIDITY:

H (+1) ? I

U (-1) ? T

M (+2) ? O

I (-2) ? G

D (+3) ? G

I (-3) ? F

T (+4) ? X

Y (-4) ? U

So, new word:

I T O G G F X U

Let's check which option matches:

- Option 1: GVJMXOMG

- Option 2: IWJNYOMG

- Option 3: IVJNYOMH

- Option 4: GWJMYOMG

None match ITOGGFXU.

So, here's what’s going on. The answer given in any option doesn’t fully fit a clear logical pattern. But based on the letter shifting (first letter H->G, U->W?), Option 4 starts with G but next is W (U->W is forward, not backward).

So the correct answer is Option 1: GVJMXOMG; it at least fits the more consistent letter shift pattern.

.

Here’s a summary:

- AQUARIUM to ZSREMONU follows a shifting pattern, mostly backward by one place.

- Applying the same logic to HUMIDITY, you’d get something starting with 'G' as HUMIDITY’s first letter shifted backward is 'G'.

- Of all the options, Option 1: GVJMXOMG fits closest to the expected letter shift pattern.

- ?? Option 1 is the answer: GVJMXOMG.
