Answer:
The last 2 point in the given question is the correct answer to the given question i.e
- an argument passed to the function in the correct positional order
- an argument wherein the number of arguments in the function call should match the definition of the function.
Explanation:
The required argument are those argument that are passing to the method the in the right location order.In the required argument the number of arguments in the call method must match the definition of the function .
For example
def fun( s ): #function definition
print(s) #display s
fun('er')#calling
In this example there is function fun() in which we pass the argument 'er' we call that function from main() .The control moves to the function definition it checks the number of argument in the calling function fun() is matched with the definition of function fun() and print 'er'.
All the other option are not describing the required argument that's why this is incorrect option .
