Step-by-step explanation:
Big Data refers to large and complex datasets that traditional data processing methods may struggle to handle. Social Media Data (Option A) encompasses vast amounts of information generated from social media platforms, including posts, comments, and user interactions. Sensor Data (Option B) involves data collected from various sensors, such as IoT devices, capturing real-time information like temperature, movement, or environmental conditions.
Emails (Option C) contribute to Big Data due to the enormous volume of emails exchanged globally, including content, attachments, and metadata. In contrast, Excel Spreadsheets (Option D) typically do not fall into the category of Big Data as they represent structured data and are generally manageable with conventional database systems.
