Answer:
The answer to your question is sample A and sample C.
Explanation:
Melting point is a physical property of substances, physical properties do not depend on the amount of matter, so it doesn't matter that in one sample we have 5 kg and in the other we have 2 kg.
Besides in samples B and C we have the same amount of matter, they are different substances(copper and iron) so, their melting points are different.
Also, in samples A and D, we have the same amount of matter, but they are different substances so their melting points are different.
If both of them were travelling anti parallel to each other. (parallel but in opposite directions)
