C) pop()
D) concat(array1,array2,...)
E) sort()
F) copyWithin(target,start[,end])
G) join(separator)
H) shift()
I) reverse()
J)push(values)

Accepted Answer

The method copyWithin() duplicates items within an array by copying a sequence of elements within the same array. It takes a target index that specifies where to copy the sequence to, and a start index and optional end index that specify which elements to copy.

Answer: D
 The method concat() creates a new array that contains the elements of the original array, followed by the elements of one or more arrays passed as arguments. This effectively duplicates the items within an array.
