Select the option that is related to the third letter-cluster in the same way as the second letter-cluster is related to the first letter-cluster.NGO : PTQ :: LHT : ?

Let's find the shifting pattern from NGO to PTQ using alphabetical positional values:N (14) + 2 = P (16)G (7) + 13 = T (20)O (15) + 2 = Q (17)Let's see if the middle letter shift follows a different rule, like opposite positions or a simple addition. Let's apply $+2,+12,+2$ or similar to LHT:L (12) + 2 = N (14)H (8) + 12 = T (20) or H (+11) $\to$ S? Let's check Option A (NSV) and Option B (NJV).If the middle letter shifts from H to J, that is $+2$. If it shifts from H to S, that is its opposite letter!Let's check the middle letter of NGO $\to$ G. The opposite letter of G is T.So the middle letter is replaced by its opposite alphabet letter!Let's apply this rule ($+2$, Opposite, $+2$) to LHT:L (12) + 2 = NH $\to$ opposite letter is ST (20) + 2 = VThis gives the resulting cluster NSV.
