Question

multiple choice question
commerce among the states is called ________ commerce.
o internal
o intrastate
o intestate
o interstate

Explanation:

To solve this, we analyze the prefixes: "inter - " means between, "intra - " means within. Commerce among states (between states) is "interstate". "Internal" is too general, "intrastate" is within a single state, and "intestate" is unrelated (about property without a will).

Answer:

D. interstate
