Consider the following dictionary

Book = {1 : "Informatics Practices", 
        2 : "Computer Science ",
        3 : "Information Technology"}

Jaya executes statement: 2 in Book

Assertion (A): For the above dictionary Book, the output of the statement 2 in Book is True.

Reasoning (R): For Dictionary, the ‘in’ and ‘not in’ operators return True or False.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

For a given list

L = [1, 2, 3, 4, 5, 6]

the index of element 4 will be:

Assertion (A): The index of element 4 will be 3 or -3.

Reasoning (R): Python list supports forward and backward indexing with -1 to given to left most and 0 to right most element.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

What will be the output of the following code?

for k in range(-10, 0, 2):  
    print(k)
