In personalized healthcare, which data source provides continuous, real-time physiological measurements to dynamically update a patient's digital twin?

### Why this is right - **A** is correct: the paper includes medical history as a source for the model. - **B** is correct: results over time help represent changing health rather than a single snapshot. - **C** is correct: genetic markers may be included if the patient provides them and consents. - **D** is correct: wearable readings are named as another possible source. ### The concept A Digital Twin is intended to combine information that describes a person's health from different angles. Clinical records and test results describe documented care and measurements; genetic markers can contribute biological information, and wearable readings can add ongoing observations. The paper does not say every patient must supply every data type. Consent and availability shape what enters a person's model. ### Terms - **Genetic marker**: A measurable feature of genetic information that may be associated with a biological trait or risk. - **Wearable-device reading**: A measurement collected by a device worn on the body. ### Remember The twin can draw on several sources, but the paper makes additional sensitive sources conditional on patient consent.
