Answer:

The 3rd sentence is the wrong one:

'All carbohydrates have the general formula Cn(H2O)n'

Explanation:

This is wrong because it's a formula that holds true for simple sugars, but not for complex ones.

Take sucrose as an example, its formula is C12H22O11. Clearly it's C12(H2O)11.

This is so, because when a glycosidic bond is formed, it does so with the loss of a water molecule; hence the reaction is called condensation.
