Find the number of water molecules "embedded" in sucrose

Recently I got a question as follows:



> 
> How many molecules of water are joined with 12 atoms of carbon in a molecule of sucrose ?
> 
> 
> (A) 12 
> 
> 
> (B) 11 
> 
> 
> (C) 6 
> 
> 
> (D) 10
> 
> 
> 


I am unable to understand the question.
What actually is the question ?




* Sucrose is a [carbohydrate](https://en.wikipedia.org/wiki/Carbohydrate). This means that stoichiometrically, it can be regarded as adding water ($\ce{H2O}$) to elemental carbon $\ce{C}$.
* The formula of sucrose is $\ce{C12H22O11}$.
* Another way to write this formula is $\ce{C12(H2O)11}$.
* Thus, sucrose can be regarded (stoichiometrically, but not structurally) as eleven waters plus twelve elemental carbons. Therefore ***the correct answer is (b)***.
* The question is not well-worded, and would be better stated as "*How many water molecules are required to join with the 12 carbon atoms in sucrose to give the correct empirical formula for sucrose?*".
* In the comments Ivan Neretin offers an even better variant, which I will re-word as "*How many water molecules could extremely powerful dehydrating agents such as $\ce{H2SO4}$ or $\ce{SO3}$ extract from sucrose, if we assume the only non-water product is pure carbon?*".
