Video Summary

The task involves determining which two pieces can complete a chessboard by rotating the pieces but not flipping them. Upon examining each piece, it's determined that piece 2 and piece 4 won’t fit in any orientation. Consequently, options involving pieces 2 and 4 are eliminated. With pieces 1, 3, and 5 remaining, piece 5 fits in one segment of the board. By rotating piece 1, it fits appropriately while maintaining the chessboard's alternating black-and-white pattern. Thus, the correct pieces to complete the chessboard are pieces 1 and 5, corresponding to option B.
