In the given reaction, the quark composition of the n is (udd) and the quark composition of the K⁺ is 11ea800b_193b_3e6d_846e_f5d2be2e6192_TB6864_11 which can be written as (u¯s + s¯u). Now, in order for the strong interaction to conserve quark flavor, the quark composition of the Σ^- must be such that the sum of quark flavors before and after the reaction remains the same. The quark flavors before the reaction are: u: 2 d: 1 s: 0 The quark flavors after the reaction (excluding the K⁺) are: u: 1 d: 1 s: 0 Therefore, the quark composition of the Σ^- must be (sdd) to conserve quark flavor. This can be written as (s¯u - d¯d), which gives us the answer as (dds).
