B) df = df.filter(F.col("transaction_id").isNotNull())
C) df = df.dropDuplicates(["transaction_amount"])
D) df = df.dropDuplicates()

B) It ensures that the join happens only when the id values are identical.
C) It increases the partition size for df1 and df2.
D) It reduces the number of shuffle operations by replicating the smaller DataFrame to all nodes.
