C) More is preferred to less
D) Completeness
E) both A and C

Diminishing Marginal

A principle stating that as additional units of a variable input are added to a fixed input, the additional output produced from each new unit will eventually decline.

Indifference Curves

A graphical representation of different combinations of goods or services among which a consumer is indifferent, showing preferences and trade-offs.

Completeness

In the context of preferences, the assumption that any two bundles of goods can be compared, meaning a consumer can decide if one is preferred, the other is preferred, or they are valued equally.
