After analyzing the pattern r__t__, I notice I've already guessed the common vowels (a, e, i, o) but none appear in the word except possibly at the end. The letter 'n' is one of the most frequent consonants in English and could fit in multiple positions. Words like "rhythm", "rotten", or "certain" follow similar patterns. Given that 'n' appears frequently in English words, especially at the end of words, it's my best strategic choice with only one wrong guess remaining.
