<h2>Answer:</h2>

The correct answer is the D which 2,1,2,1.

<h3>Explanation:</h3>

In a balanced chemical equation, the number of particular atom on the right side of the equation is equal to the number of that atom on the left side of the equation.
As in the left side of the equation, there are 2 F atom and 1 Br. While on the right side there are 1 F and 2 Br. S for the balancing, we will put coefficient to the equation.
And the equation will be:

2NaBr + CaF2 → 2NaF + CaBr2

D.
2NaBr + CaF2 --> 2NaF + CaBr2 gives you:

2Na 2Na
2Br 2F
1Ca 1Ca
2F 2Br

This is balanced.
