Answer is B
Explanation:
To form a triangle using three given lengths,
one should check that
the sum of smaller two sides is greater than the largest side.
Among te given cases
A) 6 cm, 8 cm, and 16 cm
B) 6 cm, 8 cm, and 10 cm
C) 6 cm, 7 cm, and 14 cm
D) 6 cm, 7 cm, and 20 cm
this is so only in case B.
Hence, we can form a triangle only with sides given at B.
