Answer:
C
Explanation:
Single replacement reactions is when only one element gets replaced / changed. This usually looks like this: A + BC = B + AC or A + BC = C + AB
Therefore, the number of reactants must be equal to the number of products, since no actual combinations / break ups are occurring.
Answers A and D are eliminated right away since the number of products don't equal the number of reactants.
Answer B is wrong because it does not show simply one element being replaced, instead, two compounds are being formed. It doesn't look like the example given.
Only answer C shows that one element is replaced:
The iodine is replaced with bromine to form NaBr + I2
