GraphQL - Resolvers

Given the GraphQL query:

{ user(id: 3) { name age } }

What will be the result if the user with id=3 has name "Alice" and age 30?

A{ "data": { "user": { "id": 3, "name": "Alice" } } }

B{ "data": { "user": { "name": "Alice", "age": 30 } } }

C{ "data": { "user": { "name": "Alice" } } }

D{ "error": "User not found" }

Step-by-Step Solution

Solution:

Step 1: Understand the query fields
The query requests the user with id 3 and asks for the fields name and age.
Step 2: Match the expected output
The response should include both name and age for user 3. { "data": { "user": { "name": "Alice", "age": 30 } } } matches this exactly. { "data": { "user": { "id": 3, "name": "Alice" } } } includes id which was not requested. { "data": { "user": { "name": "Alice" } } } misses age. { "error": "User not found" } is an error which is incorrect since user exists.
Final Answer:
{ "data": { "user": { "name": "Alice", "age": 30 } } } -> Option B
Quick Check:
Requested fields = name, age; output matches [OK]

Quick Trick: Output matches requested fields exactly [OK]
