Respuesta :

Answer:

[tex]D[/tex]

Explanation:

Here, we want to get the combination that would react spontaneously under standard conditions

Let us take a look at option D

The reduction potential of the Mercury (ii) ion is higher than that of iodine

This means while the mercury ion will be oxidized, the iodine would be reduced

Thus, we have a spontaneous reaction taking place
