Second is the answer is correct (99% sure)
Answer:
c
Step-by-step explanation:
In the experimental design we are choosing a random rats from both sets either male and female.
each set contains 2 elements (A,B), where A is a Female i.e F1, F2,F3,F4
and B is a male i.e M1,M2,M3,M4.
none of the sets can have 2 male or 2 female.
Only option 'C' has sets which contains B (F3, F2) and D (M3, M4) which is impossible.
Hence c is the answer.
