Lets revise few concepts RAML which can help us to find the answer of this question.
URI Parameters
Lets have a look at below example.
* /foos:
* /{id}:
* /name/{name}:
Here, the braces { } around property names define URI parameters. They represent placeholders in each URI and do not reference root-level RAML file properties as we saw above in the baseUri declaration. The added lines represent the resources /foos/{id} and /foos/name/{name}.
Query Parameters
Now we'll define a way to query the foos collection using query parameters. Note that query parameters are defined using the same syntax that we used above for data types:
* /foos:
* get:
* description: List all Foos matching query criteria, if provided;
* otherwise list all Foos
* queryParameters:
* name?: string
* ownerName?: string
Based on the above information , below is the only option which defines storeid as uri parameter and department as query parameter.
* /{storeId}:
* get:
* queryParameter:
* department:

This kind of questions are best solved with filtering technique. Key thing to note here is XML attributes are always access by @ notation. So in this example orderId can be accessed as @OrderId which makes option 3 and option 4 false. Now difference in optin and option 2 is in mapping of lineItemPrice. Correct syntax to format a String in Numbse is value.price as Number. Hence option 2 is correct
