Based on statement 4, we can say that the two triangles are not congruent since Side YX is shorter than side BA. We can eliminate Option 3.
Based on Statements 3 and 4, we can say that the ratio of the two corresponding sides of the triangle XYZ and ABC are not proportional.
The two ratios are not equal because YZ and BC are congruent. This means YZ/BC = 1. On the other hand, since XY < BA, then XY/AB is less than 1.
Since the ratio of the corresponding sides is not equal, the two triangles are not similar as well. With this, we can eliminate Options 1 and 2.
Hence, the answer is Option 4. No relationship can be determined between Triangle YZX and Triangle BCA.
