All right, well, chemistry requires precision.
So to be a good chemist, we can't just take
a handful of this and a pinch of that and expect to get the result we want.
And the same thing goes for science lingo.
The words scientists use have precise meanings.
So with that, we can immediately rule out option A - supply
because it lacks that precision. Like, it could be anything.
The word "supply" isn't specific to materials involved in a chemical reaction.
We can also get rid of option C because the word "resultant"
isn't really a word used in chemistry.
But even so, we can tell that it wouldn't be right because
the question is about starting materials, not the result.
All right? All right. Well, D's out, too.
The product is what the chemical reaction produces.
It's what we end up with. The answer we're looking for is B - reactant.
Reactants are the starting materials of a chemical reaction.
Think of bread. Ingredients:
the water, the yeast, the flour, the salt.
Those are the reactants.
And when you put them together and add heat for a while,
the product is just a big fat loaf of yumminess. Yum. Bread.
All right, we just need to be careful not to eat all of our science
in one sitting. Otherwise, well, there could be a bad chemical reaction.
Yeah. Stomach ache. You don't wanna go there.
