Answer:
C. EXCLUDABLE and RIVAL in consumption
Step-by-step explanation:
A good is EXCLUDABLE if it is feasible to exclude people from consuming it , can be restricted to entirely private consumption based on price mechanisms .
A good is RIVAL if its consumption by one consumer doesnt reduce its availability to be consumed by other consumers .
CHEESEBURGER - Feasibly excludable among potential consumers as per price purchase,
It's consumption by a consumer reduces its availability for other consumers
Is a PRIVATE GOOD , which is both Excludable & Rival
This can be better explained with example of -
Public Goods (Non Rival , Non Excludable) .
Eg : Air Pollution - People cant be excluded from that , breathing of polluted air by one person doesn't reduce the pollutedness of air for other breathing people
