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. CART : UTDG :: DREW : XGUH :: ENDS : ?

Let's investigate the pattern between CART and UTDG:Instead of a direct linear shift, let's check the reverse mapping of the word (reading from right to left): T (+1) $\to$ UR (+2) $\to$ TA (+3) $\to$ DC (+4) $\to$ GLet's cross-verify with DREW : XGUH:W (+1) $\to$ XE (+2) $\to$ GR (+3) $\to$ UD (+4) $\to$ HThe logic is perfectly consistent: reverse the order of letters, then apply shifts of [+1, +2, +3, +4].Let's apply this rule to ENDS:S (+1) $\to$ TD (+2) $\to$ FN (+3) $\to$ QE (+4) $\to$ IHence, the resulting cluster is TFQI.
