Q46 Single choice

The code block shown below contains an error. The code is intended to print the schema of DataFrame storesDF.

Identify the error.

storesDF.printSchema().getAs[String]

A
printSchema() is not a member of DataFrame; getSchema() should be used instead.
B
printSchema() is not a member of DataFrame; schema() should be used instead.
C
The entire expression must be converted to a string before it can be printed.
D
printSchema() already prints the DataFrame schema and does not return a Row, so getAs[String] cannot be called on its result.
E
The schema must first be retrieved with schema and then passed to print().
