Which of the following is NOT a complex type in Avro schema definitions?

Explanation:
In Avro, types are split into primitives and complexes. Complex types are structures that organize or contain other data: a Record defines a structured object with named fields, an Array represents a list of items of a certain type, and a Map holds key-value pairs with string keys and values of a specified type. Primitive types, on the other hand, are atomic building blocks like string, int, boolean, long, float, double, bytes, and null, which do not group data or hold collections. So, the type that is not a complex type is the string type. It represents text data as a single value and is not a container or structure, unlike Record, Array, or Map.
