The two shortest sides have to add up to be bigger than the longest side.
A. 17,12,6 6+12= 18 18>17 <- this is a triangle
B. 25,13,38 25+13= 38 38=38 <- this is NOT a triangle
C. 14,27,36 14+27= 41 41>36 <- this is a triangle
D. 39,44,6= 39+6= 45 45>44 <- this is a triangle
The answer is B.
I hope this helps!
