GraphQL - Resolvers

Identify the error in this resolver code snippet:

const resolvers = {
  Query: {
    userAge: (parent, args) => {
      return args.age
    }
  }
};

// Query: { userAge }
// Variables: {}

AMissing context parameter in resolver

BResolver expects argument 'age' but none provided in query

CResolver should return parent instead of args.age

DSyntax error: missing semicolon after return

Step-by-Step Solution

Solution:

Step 1: Check resolver parameters and usage
The resolver expects an argument named 'age' from args to return.
Step 2: Analyze the query and variables
The query requests userAge but provides no variables, so args.age is undefined.
Final Answer:
Resolver expects argument 'age' but none provided in query -> Option B
Quick Check:
Missing argument in query = D [OK]

Quick Trick: Check if query provides needed args for resolver [OK]
