Atype: object properties: users: type: array items: type: object properties: username: type: string roles: type: array items: type: string

Btype: array items: type: object properties: username: string roles: array of strings

Ctype: object properties: users: type: object properties: username: string roles: string

Dtype: array items: type: string properties: username: string roles: array

Step-by-Step Solution

Solution:

Step 1: Understand the data structure
The response is an object with a "users" property that is an array of user objects.
Step 2: Check each user object schema
Each user has "username" as string and "roles" as an array of strings, so nested arrays and objects are needed.
Step 3: Match with options
Only type: object properties: users: type: array items: type: object properties: username: type: string roles: type: array items: type: string correctly nests arrays and objects with proper types and keys.
Final Answer:
type: object properties: users: type: array items: type: object properties: username: type: string roles: type: array items: type: string -> Option A
Quick Check:
Nested arrays and objects = type: object properties: users: type: array items: type: object properties: username: type: string roles: type: array items: type: string [OK]

Quick Trick: Use nested objects and arrays for complex data shapes [OK]
