When strontium hydride (SrH2) reacts with water, it forms strontium hydroxide (Sr(OH)2) and hydrogen gas (H2). The balanced equation is:

SrH2 + 2H2O → Sr(OH)2 + 2H2

However, in this question, SrHS is used instead of SrH2. This is a bit unusual, as SrHS is not a commonly known compound. However, we can still use the same general reaction for our prediction.

So, SrHS and water should form strontium hydroxide and hydrogen gas. The only answer choice that includes both of these products is B. Additionally, it also includes hydrogensulfide gas (H2S), which is likely formed due to the presence of impurities in the SrHS sample.
