Which of these sections of Google Analytics Reports provides insights into where users are coming from (e.g., social media) before visiting your website?

Acquisition is correct because the Acquisition section in Google Analytics 4 reports on how users arrive at your website, including traffic sources such as social media, organic search, or referrals. This section helps you understand which channels are driving visitors to your site and supports analysis of marketing performance, whereas Monetization, Engagement, and Demographics focus on user behavior, revenue, and audience characteristics rather than traffic origins.
