Final answer:
The function 'input()' in Python always returns a string datatype. To use this data as another type, such as an integer or float, you must explicitly convert it using 'int()' or 'float()'. (option a)
Step-by-step explanation:
The 'input()' function in Python is designed to take user input as a string. Regardless of the user entering numerical values or any other type of input, it is treated as a string by default. If you intend to use the input as a numeric value, you need to explicitly convert it to the desired data type using functions like 'int()' or 'float()'.
For example, if you want to treat the input as an integer, you would use 'int(input())'. This design choice allows for greater flexibility, as the input function can handle a wide range of input types without making assumptions about the user's intended data type.
In Python, the 'input()' function returns a string, emphasizing the language's commitment to explicit data type conversion for user inputs.
