B. 122, 257, 137
Step-by-step explanation:
The triangle inequality rule states that the sum of any two sides of a triangle must be greater than the third side. If A, B and C are sides of a triangle then A + B > C, A + C > B, B + C > A
Testing for the options:
1) 10, 20, 30
10 + 20 (= 30) is not greater than 30. It cannot form a triangle
2) 122, 257, 137
122 + 137 (259) is greater than 257. It can form a triangle
3) 8.6, 12.2, 2.7
8.6 + 2.7 (11.3) is not greater than 12.2. It cannot form a triangle
4) 1/2, 1/5, 1/6
1/5 + 1/6 (11//30) is not greater than 1/2. It cannot form a triangle

You cannot round on a calculator (at least the type I use). You need to learn how to do it yourself, if you are required to round to 3sf look at the 4th digit if it is greater than 5 you round the 3rd digit up and if the 4th digit is less than 5 leave the 3rd digit as it is
eg. 66.7223838
= 66.7
eg2. 657892354
= 658000000
