Answer: Option D. -> Error

We can't directly multiply elements of array, it will show an error
Output:
can't convert Array into Integer

Question 4. What is the output of the given code?string_array = ["a","e","i","o","u"]boolean_array = ["True","False"]puts string_array[3]puts boolean_array

[a","e","i","o","u"].
Error
c) o True False
None of the mentioned

Discuss Question

Answer: Option C. -> c) o True False

The array is a string array and the index is 3 so 'o' will be the output and then the boolean_array will get printed.
Output:
o
True
False

Question 5. What will be the output of the following?array = [100, 200, 300, 400, 500]print array[4]
