The function Double replaces each element of a list of integers with twice that element. For example, when this function receives $[2,0,-3]$ as input, the output will be $[4,0,-6].$ Incomplete code for Double is given below.

def Double$($A$)$:

for i in range$(0,$len$($A$))$:

#FIX ME#

return A

What should the line of code which contains the expression #FIX ME# be replaced with in order to complete the code?

Question $3$ options:

A$[$i$]=2*$i

A$[$i$]=2*$A$[$i$]$

i $=2*$A$[$i$]$

i $=2*$i
