Reactants are what make products, for example:

reactant + reactant -----> product + product

So in a question, when it says that 'X' and 'Y' are FORMED, it means they were created as products from the reactants. 

Same goes for when it says 'X' and 'Y' have REACTED, that means they have reacted with one another, which makes them the reactants. 

Knowing this, you can work out the answer :)
