Which set of lengths can form a triangle?

a $5, 6, 7$
b $5, 7, 14$
c $3, 4, 7$
d $2, 4, 8$

ব্যাখ্যা

A valid triangle requires the sum of every pair of sides to exceed the third; for $5, 6, 7$ we have $5 + 6 = 11 > 7$ , and all other pairs satisfy this too. The other sets fail because the two smaller lengths sum to less than or equal to the largest side.
