Answers

Answer:

Explanation:

C.

The number of tobacco users has not changed.

(im not sure but i think that is

High taxes on tobacco products has not impacted the number of people who use them as the number of tobacco users has not changed. So, Option C is correct.

At present, these products are subject to a 28% Goods and Services Tax (GST) rate. The 28% rate is the highest GST rate with an additional compensatory cess. Tobacco products have a cess rate of 290%. The cess rate is calculated on the basis of the actual sale value (ADV).

According to a report by the World Health Organization, tobacco use costs the global economy over $1 trillion in healthcare costs and lost productivity every year.

Therefore the correct option is option C.
