A,B Correct answer
Explanation

In Ruby, both length and size are valid methods to get the number of elements in an array. They are aliases and return the same result. Options C and D are incorrect because size(name) and length(name) are not valid Ruby syntax - these methods must be called on the array object itself, not with the array as an argument.
