Answer:
Option A is the correct choice answer for the above question.
Explanation:
The programming concept says that every function returns some value. If the return value is not defined by the user then the function returns the garbage value otherwise it returns the defined value by the user.
The return value is defined by the user with the help of the "return" statement and with the help of the following syntax-
return value; // The return statement.
Hence the option A is right because it satisfies the above concept while the other is not because--
- Option B states that it must be longer than one line which is not correct.
- Option C states that it cannot be longer than one line but this line does not make any sense about the returned statement.
- Option D states that it describes the parameter value which is the wrong definition about the returned statement.

The JSON format is rocking. You can hence through JSON store the text, image, audio, video, etc in one go. And like the first five can be a text, the next five can be an image then again a text than video, and so on. And it is super easy to access them as well. Also, you can edit them quite easily as well. It's not that hard like the Lisp used to be in the past. And supermarket has a mix blend of the database. And modern databases like Data Lake can be very useful, undoubtedly.
You can store security type of requirements, like CCTV footage, each shop details like shop ID, Product list, shop type, electricity bill, hours of opening, floor, facilities, no. of employees, etc., and like this, we can have the details for the entire supermarket, and each shop there definitely.
