GraphQL - Mutations

Amutation { updateItem(id: "3", input: {name: "Item3", price: 20}) { name price updatedAt } }

Bmutation { updateItem(id: "3", name: "Item3", price: 20) { name price updatedAt } }

Cmutation { updateItem(input: {name: "Item3", price: 20}) { name price updatedAt } }

Dmutation { updateItem(id: 3, input: {name: "Item3", price: 20}) { name price updatedAt } }

Step-by-Step Solution

Solution:

Step 1: Confirm correct argument structure
mutation { updateItem(id: "3", input: {name: "Item3", price: 20}) { name price updatedAt } } correctly uses id as string and input as an object with multiple fields.
Step 2: Verify requested return fields
mutation { updateItem(id: "3", input: {name: "Item3", price: 20}) { name price updatedAt } } requests name, price, and updatedAt fields, matching the requirement.
Step 3: Check for type correctness
id is string, price is number inside input, which is valid.
Final Answer:
mutation { updateItem(id: "3", input: {name: "Item3", price: 20}) { name price updatedAt } } -> Option A
Quick Check:
Update multiple fields and request timestamp = mutation { updateItem(id: "3", input: {name: "Item3", price: 20}) { name price updatedAt } } [OK]

Quick Trick: Pass multiple fields inside input object, request all needed fields [OK]
