Analyzing the Options

1. Face-to-face conversation: This is often regarded as the most effective way to communicate as it allows for immediate feedback, non-verbal cues, and a personal connection. However, it lacks permanence as it cannot be revisited once the conversation ends.

2. Hard Copy: Written documents that are printed can provide a tangible, permanent record of communication. This includes contracts, reports, and letters. It is a strong contender for permanence.

3. E-mail: This digital form of communication allows for easy storage and retrieval, making it a permanent record of conversations unless deleted. Responses can be tracked, and important details can be referenced later.

4. Cellphone: While modern smartphones can store messages and calls, the level of permanence depends on the platform (e.g., text messages can be deleted, but voice mails can be saved).

Conclusion

Considering the need for permanence in communication, the best answer is: b. Hard Copy. Hard copies provide a permanent physical record that can be referenced at any time, making it the most effective choice for achieving permanence in communication.
