Explanation:

- Suffice: This means to be enough or adequate. When something suffices, it meets the needs or requirements.

- Option 1: Excessed: Not a standard English word. "Excess" generally means too much of something, but "excessed" might be meant as a verb form of "excess" which is non-standard.

- Option 2: Immatured: "Immature" is the more common form. This word refers to something that has not fully developed. While related to development, it does not relate to "suffice."

- Option 3: Satirize: This means to mock or criticize using satire. Not relevant as an antonym for "suffice."

- Option 4: Dissatisfy: Means to fail to satisfy. This is the opposite of sufficing, which is to fully satisfy or meet needs.

- Correct Answer: Option 4 - Dissatisfy
