Answer:
2. Jon prefers one soda and two slices of pizza to two sodas and one slice of pizza.
Explanation:
Completeness is the economic concept - that 'one good is atleast as good as itself'
Transitivity is that a rational consumer - if prefers good A to good B, good B to good C. Then he prefers good A to good C.
Let :- 1 soda & pizza slices be product combination A; and 2 sodas & 1 pizza slice as product combination B.
Consumer Jon finds product combination A at least as good as product combination B. But, he doesn't find product combination B as at least as good as product combination A.
So, as per above rules - Consumer prefers product combination A over product combination B.
