Hi @farnoushsalimian,

(A) is wrong because the original conditions don't force R into the first or last position, and so this rule excludes some possibilities that these rules would have allowed. Try, for example, TLHRMPS. This satisfies all the rules, and doesn't have R in first or last. Hope this helps!
