Answer:

The coefficients are: 1, 2, 1, 2

Step-by-step explanation:

To know which option is correct, we shall balance the equation. This can be obtained as follow:

SnO₂ + H₂ —> Sn + H₂O

There are 2 atoms of O on the left side and 1 atom on the right side. It can be balance by writing 2 before H₂O as shown below:

SnO₂ + H₂ —> Sn + 2H₂O

There are 2 atoms of H on the left side and a total of 4 atoms on the right side. It can be balance by writing 2 before H₂ as shown below:

SnO₂ + 2H₂ —> Sn + 2H₂O

Now the equation is balanced.

The coefficients are: 1, 2, 1, 2

Thus, none of the options are correct.
