Answer:
B.
Step-by-step explanation:
B. In structured data, each element is given a name and can be accessed using the name. The type of each element is not explicitly declared. This means that the data structure does not enforce any particular data type on any given element. This type of data is commonly used in programming languages such as JavaScript and Python, where data can be accessed using a combination of object properties and dictionary keys. Structured data provides a flexible way to organize and manipulate data, while allowing for dynamic changes to element types and values.
