Alex needs to email his graduation certificate to a prospective employer.He has only physical copies of the certificate.What device could he use to create an electronic copy of the certificate?

A) scanner
B) plotter
C) digital pen
D) projector

A scanner is the best device to create an electronic copy of a physical document. It allows the user to scan and save the paper document as a digital file, which can then be easily emailed or shared electronically. A plotter is a device used to create large-scale printouts or drawings and is not suitable for creating electronic copies of certificates. A digital pen is a device used to create digital handwriting or annotations, but it would not be able to create a digital copy of a physical certificate. A projector is a device used to display images or video onto a screen or surface and does not have the capability to create digital copies of documents.
