Which of the elements that are labeled with a circle and a number contain an error or are misrepresented?
A . 1, 10
B . 1, 8
C . 10
D . 7, 9, 10
E . 1, 4, 6, 9

Answer: B

Explanation:

1: Correct C This should just read "API" or "DataFrame API". The DataFrame is not part of the SQL API. To make a DataFrame accessible via SQL, you first need to create a DataFrame view. That view can then be accessed via SQL.

4: Although "K_38_INU" looks odd, it is a completely valid name for a DataFrame column.

6: No, StringType is a correct type.

7: Although a StringType may not be the most efficient way to store a phone number, there is nothing fundamentally wrong with using this type here.

8: Correct C TreeType is not a type that Spark supports.

9: No, Spark DataFrames support ArrayType variables. In this case, the variable would represent a sequence of elements with type LongType, which is also a valid type for Spark DataFrames.

10: There is nothing wrong with this row.
