Answer:
B and C
Step-by-step explanation:
As we know,
for lengths to satisfy a triangle it should be as follows
any two sides of a triangle should be greater than the third side
Now lets do,
A)12+5=17
two sides sum not resulting in greater than third side
So it will not form
B)10+15>24
Now next
10+24>15
Now next
15+24>10
hence it will form
C)9+22>11
Next
9+11>22
Next
22+11>9
hence it will form
D)21+7>6
Next
7+6<21
So it will not form
