   A Node.js application that connects to a database fails with the error: 'TypeError: Cannot read properties of undefined (reading 'name')' at the line 'console.log(user.name)'. The code is: 'const user = getUser(123); console.log(user.name);'. The getUser function is asynchronous. What is the most likely cause of this runtime error?

   • AThe database connection is not established, so the query fails.
   • BThe console.log statement is outside the function scope.
   • CThe user with ID 123 does not exist in the database.
   • DThe getUser function returns a Promise, and the code does not await it, so user is undefined.
