Answer:
Statement 2
Explanation:
There are some simple rules to follow when using punctuation.
Rule 1: Use a comma between two long independent clauses when conjunctions such as and, or, but, for, nor connect them.
Rule 2: If the clauses are both short, you may omit the comma.
Rule 3: If you have only one clause (one subject and verb pair), you won’t usually need a comma in front of the conjunction.
Now, lets see what statements in your question need commas.
Does statement 1 need a comma? ❌
It doesn't need a comma, because of rule 3.
Does statement 2 need a comma? ✔
It needs a comma, because giant and impersonal both modify corporation.
Does statement 3 need a comma? ❌
It doesn't need a comma, because hot and new both modify movie, common sense says a comma is awkward in this situation.
Does statement 4 need a comma? ❌
It flows well, without the need for a comma.
I'm always happy to help :)
