Id say E

AB=1. Nothing about the other sides

AB=1 BC+AC=2. BC could be anything so long as when added to AC it = 2. Nothing says the sides have to be integers.

for a triangle

sum of two sides should be greater than the third

and given a = 1 and b+c =2 can we find such numbers?

so i think here only 1,1,1 fit the case

If triangle ABC is equilateral then the ratio of AB:BC:AC has to be 1:1:1

statement 1

AB = 1

Tells us nothing about BC or AC

insufficient

statement 2

BC+AC = 2

insufficient

both statements

AB+BC+AC = 3

since we know that in any triangle two sides have to equal to or bigger then the third side. the only possibale value for AB BC or AC is 1.

If AB = 1 BC = 2 and AC = 0

then this is not a triangle.

sufficient

AB=1

BC+AC=2

1 1.4 .6

Could be this 1.4+1>.6 1.4+.6>1 1+.6>1.4

and AB=1 and BC+AC=2

Or could be 1 1 1
