A ------- B
AB > 15 ?
statement 1
A ------- C + B ------- C > 14
AC can be 2 and BC can be 13 or AC can be 1 and BC can be 14.
Insufficient
statement 2
A triangle can have an area of less then one but one side greater than 15.
Insufficient
both statements
since the area of the triangle ABC is ---> (height*base)/2 ---> but we cannot tell if AB is the height or AC or BC or which is the base.
so AC can be 1/16 (the base) where AB is the height than:
(16*1/16)/2 = 1/2 ---> less than 1
so the answer is (E)

I think it is B
AB>15?
1. doesnt def. give any idea of the points apart from points on xy plane not suff.
2. we make sure that points make traingle and its area is < 1. it might be an equilaterial traingle with sides 1 or less or any other with sides <1 so we can now assume that AB is less than 15 and say NO
but there is another version that makes it C. will explain later if i can make sure it is--- anyway, I will stick to B
