Detailed Solution & Explanation

We can determine the letter corresponding to each digit using direct substitution from the given examples:
From the word LOSE→1357\displaystyle LOSE \rightarrow 1357, we get:
L=1\displaystyle L = 1, O=3\displaystyle O = 3, S=5\displaystyle S = 5, E=7\displaystyle E = 7

From the word GAIN→2468\displaystyle GAIN \rightarrow 2468, we get:
G=2\displaystyle G = 2, A=4\displaystyle A = 4, I=6\displaystyle I = 6, N=8\displaystyle N = 8

Now, let's decode the sequence of figures 82146\displaystyle 82146 by substituting the corresponding letters for each digit:
- 8→N\displaystyle 8 \rightarrow N
- 2→G\displaystyle 2 \rightarrow G
- 1→L\displaystyle 1 \rightarrow L
- 4→A\displaystyle 4 \rightarrow A
- 6→I\displaystyle 6 \rightarrow I

Putting the decoded letters together in order, we get the word NGLAI\displaystyle NGLAI.

Hence, **Option A** is the correct answer.
