In which of the following, each data item contains at most 2 points

The correct answer is: A. List structure

A list structure is a data structure that consists of a sequence of items. Each item in a list structure can be a value, another list, or a function. The items in a list structure are ordered, and the first item in the list is called the head of the list. The last item in the list is called the tail of the list.

A list structure can be used to represent a variety of data, such as a list of numbers, a list of names, or a list of instructions. List structures are often used in computer programming, as they are a flexible and efficient way to represent data.

Here is a brief explanation of each option:

• B. LISP is a programming language that uses list structures as its primary data structure. LISP is a functional programming language, which means that it focuses on the evaluation of functions rather than the manipulation of data.
• C. List sorting is the process of arranging the items in a list in a specific order. There are many different algorithms for list sorting, and the best algorithm to use depends on the specific data set.
• D. List head is the first item in a list. The head of a list can be any type of data, such as a number, a string, or another list.
• E. None of the above is not a valid option.
