Answer:
C. layout of each page with its respective elements
Step-by-step explanation:
A layout of each page with its respective elements will give the client a good idea of the final product and help him confirm his desires/requests towards the creation of the Web site. Most people are visual, especially about things they don't fully understand, so a clear and visual representation is best.
A. Bulleted lists and titles... won't give the idea of the full layout of the Web site.
B. chart depicting.... that's more a tool for the programmer than the client, although user flow is important, it isn't as much as the visual aspect of each page.
D. pictures and screenshots of websites of other florists... That could be a useful aid on the first contact, but the question implied the Web site is already in progress... so that wouldn't help much.
E. programming code for the website, absolutely not, the client hired Jeremy not to have to deal with that.
