A developer initializes a SparkSession:spark = SparkSession.

Comprehensive and Detailed Explanation From Exact Extract:

According to the PySpark API documentation:

"getOrCreate(): Gets an existing SparkSession or, if there is no existing one, creates a new one based on the options set in this builder."

This means Spark maintains a global singleton session within a JVM process. Repeated calls togetOrCreate()return the same session, unless explicitly stopped.

Option A is incorrect: the method does not destroy any session.

Option B incorrectly ties uniqueness toappName, which does not influence session reusability.

Option D is incorrect: it contradicts the fundamental behavior ofgetOrCreate().
