Concept:Swapping two rows of a determinant flips its sign. A cyclic permutation of three rows is an even permutation (two swaps) and does not change the determinant.Explanation:Let the given determinant be D. Option A: swaps rows 2 and 3 of D — one swap — value = −D.Option B: swaps rows 1 and 2 of D — one swap — value = −D.Option C: rows appear in the order p,q,r; a,b,c; l,m,n. This is a cyclic shift: row1→row3, row2→row1, row3→row2. It requires two swaps (e.g., swap row1 and row3, then swap row2 and row3), an even permutation — value = D.Option D: interchanges rows and columns (transpose of a permuted matrix) — the determinant is not necessarily equal to D. Therefore only option C equals D.Answer:C. ​pal​qbm​rcn​​
