my feeling says that its not E), but i dont get any other choice. i dont like geometry.
1) nothing new. the stem already stated that it is a parallelogramm (unewqual sides) => insuff
2) the angle is ABC is 30. so DAB and DCB is 150. threre is no way to figure out a special triangle. => insuff
1) + 2) still insuff

(1) Gives AC - BD = 2.
Suppose BD = x. Then AC = x + 2.
Let the parallelogram be like
.................x+2
.....A.______________B
.x.../|........................../|
..../..|......................../..|
D/__|___________/__|
.......E..................C...F
Nothing gets us the differences between the diagonals (we at least need to know the individial lengths and angles to calculate the diagonals as hypotenuse of right triangles).
Thus insufficient.
(2) Angle ABC = 30.
Therefore, CF = DE = x sqrt(3)/2 and
AE = BF = x/2
[CF = x cos 30 and BF = x sin 30]
Therefore, BD^2 = (x+2 +x sqrt(3)/2)^2 + (x^2)/4
Similarly, we can compute AC^2.
But both are in terms of x (and likely the second power of it).
Therefore, their difference can't be computed without knowing the value of x.
Therefore (E).
