Select the option that is related to the fifth letter-cluster in the same way as the second letter-cluster is related to the first letter-cluster and the fourth letter-cluster is related to the third letter-cluster.
UNREAL : MCHVSA :: CREATE : FVDIWI :: AROUND : ?

The correct option is EPXSWG.

To find the logic behind the relationship, let us analyze how the first letter-cluster transforms into the second letter-cluster: UNREAL : MCHVSA.

First, we write the letters of the word UNREAL in reverse order:
L - A - E - R - N - U

Next, we add consecutive integers (+1, +2, +3, +4, +5, +6) to the positional values (A = 1, B = 2, ..., Z = 26) of these reversed letters:

$L\; (12)\; +\; 1\; =\; 13\; \backslash Rightarrow\; M$

$A\; (1)\; +\; 2\; =\; 3\; \backslash Rightarrow\; C$

$E\; (5)\; +\; 3\; =\; 8\; \backslash Rightarrow\; H$

$R\; (18)\; +\; 4\; =\; 22\; \backslash Rightarrow\; V$

$N\; (14)\; +\; 5\; =\; 19\; \backslash Rightarrow\; S$

$U\; (21)\; +\; 6\; =\; 27\; \backslash Rightarrow\; 1\; \backslash Rightarrow\; A$

This gives the cluster MCHVSA.

Let us verify this logic with the second pair: CREATE : FVDIWI.

Reversing the word CREATE gives:
E - T - A - E - R - C

Applying the addition pattern to their alphabetical positions:

$E\; (5)\; +\; 1\; =\; 6\; \backslash Rightarrow\; F$

$T\; (20)\; +\; 2\; =\; 22\; \backslash Rightarrow\; V$

$A\; (1)\; +\; 3\; =\; 4\; \backslash Rightarrow\; D$

$E\; (5)\; +\; 4\; =\; 9\; \backslash Rightarrow\; I$

$R\; (18)\; +\; 5\; =\; 23\; \backslash Rightarrow\; W$

$C\; (3)\; +\; 6\; =\; 9\; \backslash Rightarrow\; I$

This gives the cluster FVDIWI.

Now, applying the same pattern to the word AROUND:

Reversing the word AROUND gives:
D - N - U - O - R - A

Applying the addition pattern:

$D\; (4)\; +\; 1\; =\; 5\; \backslash Rightarrow\; E$

$N\; (14)\; +\; 2\; =\; 16\; \backslash Rightarrow\; P$

$U\; (21)\; +\; 3\; =\; 24\; \backslash Rightarrow\; X$

$O\; (15)\; +\; 4\; =\; 19\; \backslash Rightarrow\; S$

$R\; (18)\; +\; 5\; =\; 23\; \backslash Rightarrow\; W$

$A\; (1)\; +\; 6\; =\; 7\; \backslash Rightarrow\; G$

This results in the letter-cluster EPXSWG.
