If lmn = xyz which congruence are true by cpctc

CPCTC represents Corresponding Parts of Congruent Triangles are Congruent
. <y congruent to <N. 2. <x congruent to <L. 3. Side ML congruent to side YX. 4. <Z congruent to <N. 5. Side ML congruent to side YZ. 6. Side LN congruent to side YX 
hope yhis helps

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"
