sometimes if you type your question into a search engine instead of asking a question you may get somewhere.
No wonder your in summer school.

There are many more than three ways to prepare hydrogen, but typical ways include
electropositive metal + acid
steam reforming methane

electrolysis is the main one and easiest and safest unless you're stupid and set something on fire which is entirely possible.
react sodium or other group one metal with water and H2 is given off (normally catches on fire).
HCl + aluminum foil - do not do this near flamable materials unless you want to explain to the nice firemen exactly how you set your house on fire.

I'm not quite sure what the question is refering to. Prepare it for what? Use, storage?
