Question:Absent any actual need for choosing one method over the other, does passing arrays by value to a read-only function reduce performance compared to passing them by reference? 

A Yes, because the interpreter must always create a copy of the array before passing it to the function. 

B Yes, but only if the function modifies the contents of the array. 

C Yes, but only if the array is large. 

D Yes, because PHP must monitor the execution of the function to determine if changes are made to the array. 

E No.
