Read the excerpt from “Before Giving to a Charity.” The safest way to give on social media or through crowdfunding is to donate to people you know who contact you about a specific project. Don’t assume solicitations on social media or crowdfunding sites are legitimate, or that hyperlinks are accurate—even in posts that are shared or liked by your friends.

What is the meaning of the word solicitations?
(I looked up the word and it basically said C but I don't trust it.)

A. authentic charities found only on the Internet

B. links on a web page that lead to other pages

C. requests for help or money to support a cause

D. pictures posted on social media websites
