Question

If 3 and 8 are the two sides of a triangular region, which of the following can be the length of the third side?
I 5
II 8
III 11

a II only
b. III only
c. I and II only
d II and III only
e. I, II and III only

Now.. i got so confused with this one, that I could not even mark an answer

According to me, both I and III are possible... where as the correct answer option is a. II only...

two shorter sides added up together must be longer then the remaining third side

so 3 5 and 8 they are equal but not longer eliminate it
3 8 and 11 eliminate
3 8 8 here any two sides are longer then the remaining - OK

I just got confused with the concept.. I think

I was thinking that the sum of two sides can be equal to or greater than the third one
