2. Leave a printed copy on her supervisor's desk after working hours.

3. Encrypt it and send it via digitally signed Government e-mail.

4. E-mail it using her personal e-mail account.

#### Solution By Steps

***Step 1: Assess Information Sensitivity***

Proprietary information is sensitive and should be handled according to strict security protocols to prevent unauthorized access.

Options involving personal accounts or leaving physical copies unsecured are not secure. A shared folder may not provide sufficient security unless it has specific controls for sensitive information.

***Step 3: Determine the Most Secure Option***

Encrypting the document and sending it via a digitally signed government email provides both verification of the sender's identity and protection of the document's contents.

#### Final Answer

Encrypt it and send it via digitally signed Government e-mail.
