Your team is developing a machine learning solution on Google Cloud to classify support requests for a platform, aiming for full control over the model's code, serving, and deployment using TensorFlow. The project has tight deadlines and budget constraints, requiring an efficient approach that leverages existing resources and managed services without starting from scratch. Additionally, the solution must be scalable to handle increasing volumes of support requests and comply with data privacy regulations. Considering these requirements, what is the best approach to construct this classifier? (Choose two options if E is available)
