Hi,
array2 is two dimensional array and cannot be referenced with one dimensional array array1 so the option is A

But what makes array2 a two-dimentional array? I don't understand the syntax.

Consider the statement
"byte [] arry1, array2[];"
This is same as
byte[] arry1;
byte[] array2[];

Since the first "[]" is associated with the datatype (byte in this case), it is applicable to all the identifiers that follows (of course they should be comma seperated).
