Answer:
Title Slide
Explanation:
Marco should use the "Title Slide" pre-set layout template to make minimal sizing adjustments. Because as you can in attachment, Title slide pre-set layout allow Marco to put the presentation title and the date of the training.
Why not other options?
While in the Blank slide, Marco can't add title and date to slide because, in the blank slide layout, he needs a lot of work to do size adjustment for adding title and date.
Title only pre-set layout allows you to add the only title. If Marco, select this option, then he needs to add a text box for date and do size adjustment also.
This pre-set layout allows Marco to add title and date in the slide but does not look good. because this pre-set layout allows you to add slide title and then related content in the content area such as image, graphs, media, and text, etc. however, this pre-set is not good for the Marco requirement.
