For a certain experiment, the available experimental units are six people: three females (1) and three males (m). Use (11, 21, 31) to denote the females and (1m, 2m, 3m) to denote the males. There are to be three treatment groups: A, B, and C. If a randomized block design is used, with the experimental units blocked by
gender, which assignment of treatments is not correct?
O A: (14,1m), B: (24,2m), C: (3f, 3m)
O A: (26,1m), B: (3f, 2m), C: (11, 3m)
O A: (11,2m), B: (3f, 21), C: (3m, 1m)
A: (2f, 3m), B: (31,2m), C: (1f, 1m)
