Primary storage refers to your RAM it is internal storage.
Secondary storage is any storage that is not the primary storage that permanently stores data. Examples are hard drive, tape disk drive, floppy disk drive and compact disk drive.
Off-line storage refers to any device that stores data that is not permanently attached to the computer. Example flash drives, The data remains on the storage device and can be connected to a different computer.

Answer:
The answer is "a1 and a2 is an array of pointers".
Explanation:
In this question, A collection of pointers refers to an array of elements where each pointer array element points to a data array element. In the above-given statement, the two-pointer type array "a1 and a2" is declared that holds the same size "8" elements in the array, and each element points towards the array's first element of the array, therefore, both a1 and a2 are pointer arrays.
True. If the list contains any elements that appear more than once, then it has duplicate elements and the variable has_dups is True.
What is variable?
Throughout computer programming, a variable is indeed a named container for a specific set of bits or type of data. A variable is indeed an abstract storage location with an associated symbolic name that holds some unidentified quantity of information made reference to as a value. Eventually, a memory address may be used to link or identify a variable. In addition to using the variable name or the variable itself, depending on circumstances, the stored value is typically referenced by the variable name. The name can be used independently of the precise information it represents thanks to the separation of name as well as content. During run time, a value can be bound to an identification number in computer source code.
