All of the listed options are areas where Artificial Intelligence is commonly applied. Data entry automation: AI, often through Robotic Process Automation (RPA) and machine learning for optical character recognition (OCR), automates repetitive data entry tasks. Predictive maintenance: AI models analyze sensor data from machinery to predict potential failures, allowing for maintenance to be performed proactively. Medical imaging analysis: AI, particularly deep learning, is used to analyze medical images (like X-rays, MRIs, CT scans) to assist in diagnosis and detect anomalies. Natural language processing: NLP is a branch of AI that enables computers to understand, interpret, and generate human language, used in applications like chatbots, translation, and sentiment analysis. Therefore, all options are correct. Data entry automation Predictive maintenance Medical imaging analysis Natural language processing
