Answer: C. shift right/ out because tobacco production will become profitable.
Step-by-step explanation:
Subsidies reduce the cost of using something because the government would sponsor it. The cost of farming tobacco will therefore reduce in this instance. Tobacco companies will therefore incur less cost to acquire tobacco and so will start making more profit.
This will encourage other firms to come into the tobacco market as time goes on. As more firms enter, there will be a larger supply of tobacco. The supply curve will then shift right to depict this.
