What is the output of the print statement for the following code:

multiples $=[]$

for threeD in range$(1,3)$:

multiples.append$([])$

for twoD in range$(1,3)$:

multiples$[$threeD$-1].$append$([])$

for oneD in range$(1,3)$:

multiples$[$threeD$-1][$twoD$-1].$append$($threeD$)$

print$($multiples$)$

$[[[1,2,3],[1,2,3]],[[1,2,3],[1,2,3]]]$

$[[[1,1],[2,2]],[[1,1],[2,2]]]$

$[[[1,1],[1,1]],[[2,2],[2,2]]]$

$[[1,2],[1,2],[1,2],[1,2]]$
