GraphQL - Resolvers

Why is the info argument included in a GraphQL resolver function signature even if often unused?

AIt contains the authentication token for the request

BIt is required to access the arguments passed to the query

CIt holds the parent resolver's return value

DIt provides details about the execution state and query AST for advanced use cases

Step-by-Step Solution

Solution:

Step 1: Understand the purpose of info
Info contains the abstract syntax tree (AST) of the query and execution state, useful for advanced features like query analysis or optimization.
Step 2: Differentiate info from other arguments
Authentication is in context, parent holds previous resolver result, and args hold query arguments.
Final Answer:
It provides details about the execution state and query AST for advanced use cases -> Option D
Quick Check:
info = query AST and execution details [OK]

Quick Trick: Info holds query details, not auth or args [OK]
