It seems like you're asking about the correct form of a verb tense. The phrases "is making," "are making," "have been making," and "were making" are different forms of the verb "to make" in various tenses.
- is making: Present continuous (used for actions happening right now)
- are making: Present continuous (also used for actions happening right now, but with plural subjects)
- have been making: Present perfect continuous (used for actions that started in the past and are still continuing or have recently finished)
- were making: Past continuous (used for actions that were happening at a specific time in the past)
To determine the "correct" answer, I'd need more context about what you want to express. Could you provide a specific sentence or situation?
