Explanation:

Alright, let’s dig in:

- First, let's check the logic behind the code.

- 'SAFETY' = 95 and 'EXPAND' = 87.

- If you sum up positions of their letters (A=1, B=2,...,Z=26):

- SAFETY: S(19) + A(1) + F(6) + E(5) + T(20) + Y(25) = 76

- EXPAND: E(5) + X(24) + P(16) + A(1) + N(14) + D(4) = 64

- These totals don’t give 95 or 87.

- Next, difference between the code and the letter sum:

- 95-76=19, 87-64=23.

- The pattern doesn’t seem to be a direct sum or product. Let’s try multiplying the first and last letters:

- SAFETY: S(19)*Y(25)=475

- EXPAND: E(5)*D(4)=20

- That doesn’t fit either. Let's try the simple sum of squares of each letter: super high values, so, not likely.

- Instead, look at the answer options. For GATHER:

- G(7)+A(1)+T(20)+H(8)+E(5)+R(18)=59

- Let's check if for the previous words, there's a pattern in the difference between code and letter sum:

- Both code numbers are higher than the sum by reversed order (no clear match).

- Let's try multiplying sum of first and last three letters:

- SAFETY: S+A+F=19+1+6=26; E+T+Y=5+20+25=50; 26+50=76

- Doesn't fit.

- Honestly, the coding logic isn’t crystal-clear with the data given. So, in these situations, look at how the numbers compare.

- 'GATHER' isn’t close to 86 by any of the tested patterns.

Here’s what it actually is:

- Let's compare sample answers to the code numbers. They all hover around the 80s and 90s for six-letter words.

- If we take the option closest to the codes for similar-length words: 'SAFETY' (95), 'EXPAND' (87), so it's likely GATHER would code near 87-95.

- Only option 3, 88 fits the expectation by proximity and range set by the examples.

So the correct answer is:

Option 3, 88.
