This regulatory mechanism is in conjunction with the endocrine system, particularly in the posterior pituitary gland. This is related in the secretion of vasopressin or antidiuretic hormone (ADH). In the event of dehydration or extreme thirst, the body will conserve as much fluid as possible and the posterior pituitary will secrete more ADH that will signal the kidney to reabsorb more water in the collecting tubules.

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.
