Explanation:
* To use custom modules, you need to import the module or functions you want to use by adding the import directive to the head of your DataWeave script, for example:
1) Does not identify any functions to import from the String module: import dw::core::Strings
2) To identify a specific function to import from the String module: import camelize, capitalize from dw::core::Strings
3) To import all functions from the String module: import * from dw::core::Strings
The way you import a module impacts the way you need to call its functions from a DataWeave script. If the directive does not list specific functions to import or use * from to import all functions from a function module, you need to specify the module when you call the function from your script.
* In given scenario, it's mentioned to import all of the WebStore.dwl So correct answer is:
