We have a right triangle so we need to use the Pythagorean theorem in order to know if the values given could be in triangle ABC.
The Pythagorean theorem is

for
a=3
b=4
c=5


It is a right triangle because we satisfy the Pythagorean theorem
For
a=10
b=8
c=6


The results are not equal therefore it is not a right triangle
For
a=5
b=12
c=13


It is a right triangle because we satisfy the Pythagorean theorem
For
a=1
b=1
c=2


The results are not equal therefore it is not a right triangle
