Which approach should you recommend?

You manage your companys SharePoint 2010 development efforts. Your company has hired an outside vendor
to print its marketing materials. The head of the marketing department has asked you to design a plan to add
functionality to the intranet site that will allow company employees to submit their print orders to a SharePoint list
on the intranet site throughout the day. The vendor should receive a daily e-mail that shows them all the orders
that were submitted to the intranet site the day before. Your plan needs to make this functionality possible.
Which approach should you recommend?

A.
Create a custom workflow that generates an e-mail with order details and sends it to the vendor.
Attach the workflow to the list and configure it to execute each time an item is added to the list.

B.
Create an event receiver that generates an e-mail with order details and sends it to the vendor.
Attach the event receiver to the Item Adding event on the list.

C.
Create an event receiver that generates an e-mail with order details and sends it to the vendor.
Attach the event receiver to the Item Added event on the list.

D.
Create a timer job that retrieves all the orders submitted to the SharePoint list, generates an e-mail containing the order information, and sends it to the vendor.
Schedule the timer job to run each morning.
