Answer:
Option (1) is correct.
Step-by-step explanation:
The pepperoni is the ingredient of pizza and used as an input in the market of pizza. Hence, if there is a fall in the price of the pepperoni then as a result this will reduce the cost of production of pizza makers.
This would increase the supply of pizza and there is a fall in the price of pizza because of lower cost of production of pizza. There is a rightward shift in the supply curve of pizza.
