Answer:
C). Jovanna visited France, Spain, and Italy on her summer trip to Europe.
Step-by-step explanation:
Punctuation demonstrates the signs or typographical devices that help to correct reading and understanding of the written word or sentence. It illustrates a set of symbols(terminal points, pausing points, hyphens, and dashes) that clarify meaning by separating strings of words into phrases, clauses, and sentences and illustrating its structure(construction). As the given sentence includes the items in a series that is separated by using a comma. Thus, the correct answer is option C as it appropriately employs comma.
