What should be avoided when shipping items to members?

The correct choice is related to the importance of safeguarding member information and ensuring a smooth shipping process. Specifically, leaking a member's personal information can lead to serious privacy breaches and a loss of trust in the service provided by the Optical Department. Personal information is sensitive and must be handled with utmost care; any exposure can have significant repercussions both for the members and the company.

Using ground shipping for urgent needs, while a consideration, does not fundamentally compromise member trust or safety like leaking personal details does. Offering multiple shipping options is typically beneficial and allows for flexibility, and delaying shipping times may frustrate members but does not breach their privacy. Therefore, protecting personal information is paramount in maintaining the integrity of the service and ensuring customer satisfaction.
