From 2018, a levy was charged on soft drinks with a high sugar content. Which outcome would show that the levy had helped to correct the market failure linked to sugary drinks?

The levy raises money that the NHS spends on treating tooth decay, while the total sugar bought in soft drinks stays the same
Manufacturers keep their recipes and pass on the levy, so the price of high-sugar drinks rises while the quantity bought stays the same
Manufacturers cut the sugar in their drinks, but sales rise so much that the total sugar bought in soft drinks stays the same
