What is the method to create a new instance of the SparkConf class?

The method to create a new instance of the SparkConf class is to use the constructor syntax associated with that class, which is represented as new SparkConf(). This approach is standard in Java and Scala for instantiating objects from classes.

Using new SparkConf() effectively calls the constructor of the SparkConf class, allowing you to initialize a configuration object for your Spark application. This object is crucial for setting various configuration options, such as the application name, the master URL, and other settings that define how the Spark application behaves.

The other choices do not align with the Object-Oriented Programming practices for instance creation. Options like new SparkConfig(), create SparkConf(), and init SparkConf() either reference incorrect class names or utilize incorrect syntax for instantiation, which would lead to compilation errors or runtime exceptions.
