Answer :
Answer:
Option B. Increase, because premium bottled water and carbonated sodas are substitutes.
Explanation:
The compliments are used together no apart. The example includes Tennis Balls and Rackets, automobile and petrol, etc. It means that they are compulsory for each other and their existence is dependent on the other. No one will buy tennis rackets if they don't have access to tennis ball.
On the other hand, substitute means that you have an alternative thing which will fulfill you needs. If the weather is hot and you don't have access to cold drinks then you can drink juice or cold water. Substitute fulfills our desires if we can't access the desired items.
Now coming back to question, the tax on carbonated water will increase the price of Soda which means its demand will decrease and people try substitutes. The substitute is either water or juice. If the coffee is 5 times expensive than tea then you will choose tea not coffee. Hence the demand of bottled water and juices will go up.
Hence the option B is correct here.
