   A developer is writing a trigger that runs after insert on the Account object. The trigger calls a method that performs a SOQL query to retrieve related contacts. The developer notices that the trigger is consuming a significant number of SOQL queries. What is the best practice to avoid hitting the SOQL query limit?

   • AMove the SOQL query outside of any loops and use a single query to retrieve all needed data.
   • BUse a @future method to perform the query asynchronously.
   • CUse a batch Apex class instead of a trigger to process the records.
   • DUse a static variable to cache the query results so they are only run once per transaction.
