HBr will produce the largest amount of solid precipitate once it is added to the test tube.

Explanation:

The reaction of silver bromide (AgBr) with the following reactans gives:

AgBr(s) + HNO₃ → AgNO₃(aq) + HBr

AgBr(s) + 2NH₃ → Ag(NH₃)₂⁺(aq) + Br⁻

2AgBr(s) + CaF₂ → 2AgF(aq) + CaBr₂

AgBr(s) + HBr no reaction

As you can see, HNO₃, NH₃ and CaF₂ react with the solid AgBr to produce soluble compounds decreasing the amount of solid precipitate. As HBr doesn't react with silver bromide, its concentration will not decrease and, for that reason, HBr will produce the largest amount of solid precipitate once it is added to the test tube.

I hope it helps!
