Correct Answer:
C. Adequate
The question asks for the meaning of “Sufficient.”
- Adequate is the correct answer. “Sufficient” means enough; adequate. Therefore, “adequate,” meaning satisfactory or acceptable in quality or quantity, or just enough, directly matches the meaning.
- Hope refers to a feeling of expectation and desire for something to happen. It is an emotion, not a measure of quantity or quality.
- Optimism is a state of mind characterized by hopefulness and confidence about the future. It is also an emotion or outlook, not a synonym for “sufficient.”
- Humanitarian relates to promoting human welfare. It describes a person or action focused on human well-being, not a quantity or sufficiency.
