Answer: Hello!
You have 1 liter of water separated in 1000 cubes, and you want to know how much contains each cube:
1 liter is equivalent to 1000 mL
then if you divide 1 Liter of water into 1000 equal parts, it has sense to separate it on 1000 cubes of 1 mL each.
But also you can see that 1mL = 1 cm³
Then is equivalent to separate 1 Liter of water in 1000 mL or un 1000 1 cm³.
Then the correct options are A and B.
