Answer: A and B
Step-by-step explanation:
The answers correct because, both of them consist of two 31 to 40s. and eight 41 to 50s. and four 51 to 60s. The problem with C is that it has three instead of two 31 to 40s, and seven 41 to 50s. And D doesnt even have the amount of numbers you need.
Hope This Helps!
