You receive an e$-$mall marked important from your boss asking for data that they need immediately for a meeting starting now. The e$-$mall was sent from a personal e$-$mall address that you do not recognire, but it addresses you by name. What concern does this e$-$mail pose?

The data must be encrypted before you can send it to a non$-$government e$-$mail address.

This poses no concern. The e$-$mail addresses you by name, so it is probably legitimate.

This is an important request that pquires your immediate attention. You may not be able to send the data in time.

This may be a spear phishing attempt. Contact your boss using contact information that you know to be legitimate.
