Solution(By Examveda Team)

The correct answer is Option A: Returns an enumerate object that produces pairs of index and value.
The enumerate() function in Python is used to iterate over a sequence while keeping track of the index of each item.
It takes an iterable as an argument and returns an enumerate object that produces tuples containing the index and value of each item in the iterable.
For example:

my_list = ['a', 'b', 'c']
for index, value in enumerate(my_list):
    print(index, value)
# Output:
# 0 a
# 1 b
# 2 c
