12) D
We need to use the numbers 9, 5 3 and -2 to make the scores given to us for each team
Crosswords: 22
9 + 5 + 5 + 3 = 22
Jigsaws: 21
9 + 9 + 5 + (-2) = 21
Rubiks: 24
9 + 5 + 5 + 5 = 24
Solitaires: 23
It is not possible to make 23 out of 9, 5, 3 and (-2)
Tangrams: 25
9 + 9 + 9 + (-2) = 25
Hence, D is the answer.
