Help with these 2 question and I with give 36 points away and brainliest (pics included)... Only 1 & 2 pls

Question one is B, and question two is A

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.
