To answer this question, you need to understand the concept of data-binding in the context of data-aware controls.
Data-aware controls are components used in software development to bind data from a data source (such as a database) to user interface elements (such as forms or grids). These controls are designed to automatically update their content based on changes in the underlying data source.
In this context, the correct answer is A) Dataset. Data-aware controls bind to a dataset object, which acts as a container for data retrieved from a data source. The dataset object can be populated with data from a database using a data adapter, and the data-aware control then binds to this dataset to display and manipulate the data.
Option B) DataAdapter is incorrect because a data adapter is responsible for retrieving and updating data from a database, but it is not the object that the data-aware control binds to.
Option C) Connection is incorrect because a connection object is used to establish a connection to a database, but it is not the object that the data-aware control binds to.
Option D) Both a and b is incorrect because only option A (Dataset) is the correct answer.
Option E) All of the above is incorrect because options B (DataAdapter) and C (Connection) are not the objects that the data-aware control binds to.
Therefore, the correct answer is A) Dataset. This option is correct because data-aware controls bind to a dataset object to display and manipulate data from a data source.
