var myrdd = Array(1,2,3,4)
This command has created rdd in scala ,so how is this the correct option?

Hi, Vaibhav.

var myrdd = Array(1,2,3,4)
Will create just an array in scala donn't get confused with the name myrdd. To create an rdd you need to a SparkContext- "sc" object to make it an rdd.
All the best!

can you explain why this line is the answer?
var myrdd = Array(1,2,3,4)
I am able to run it and can run command myrdd.take(2)

Hi David Lee,

We have "take" method in Array collection also, so myrdd.take(2) will return first two elements in the array. It is not related to RDD
