Use the scenario below to select the best answer choice for the bolded question.

Jenn, an undergraduate BIO$1130$ student, conducted a research project over the course of the semester in lab. Her research investigates the effects of various natural fertilizers on plant growth. Excited and eager to share her findings, Jenn is tasked with creating a scientific poster to effectively communicate her research for her final project in her lab that she will present to her peers at an undergraduate research conference. She has gathered substantial data and is now focusing on how best to design her poster. Jenn wants to make sure her poster is not only informative but also visually appealing to engage her audience.

Jenn starts by sketching a layout on paper, noting where her title, introduction, methodology, results, and conclusion will be$.$ She remembers that her IA and lab coordinator emphasized the importance of a coherent and logical flow of information. Jenn also plans to include graphs of her data and photographs $($also known as figures$)$ of her experimental setup. However, she is unsure about the text size, the amount of text versus visuals, and how to effectively use colors without making the poster look too busy or hard to read

Which color scheme is most appropriate for Jenn's poster if she wants it to be visually appealing but not overwhelming?

$$ Bright red and yellow for all text and backgrounds

A neutral background with color highlights for important points

Dark blue text on a black, background

All text in rainbow colors to attract attention

All of these
