Internal sorting is such a process that takes place entirely within the main memory of a computer. This is only possible whenever data items, to be sorted, is small enough to be accommodated in main memory. Hence, internal sorting do not need auxiliary storage.
External sorting is just opposite to interval sorting and used when input data, to be sorted, is very large. Hence, external sorting need auxiliary storage.

False Statement: Internal sorting is used if the number of items to be sorted is very large.
Internal sorting and external sorting are two different techniques used to sort data. The choice between internal and external sorting depends on the size of the data being sorted.
Internal Sorting:
Internal sorting is used when the data to be sorted can fit entirely in the main memory (RAM) of a computer system. It involves rearranging the data in the main memory itself, without requiring any additional storage. Internal sorting algorithms include bubble sort, insertion sort, selection sort, quicksort, mergesort, etc.
External Sorting:
External sorting is used when the data to be sorted is too large to fit entirely in the main memory. It involves using external storage, such as hard disks, to store and manipulate the data. External sorting algorithms typically involve a combination of internal sorting algorithms and techniques for merging sorted sublists. External sorting is slower compared to internal sorting due to the overhead of disk I/O operations.
False Statement Explanation:
The false statement is option 'A' which states that internal sorting is used if the number of items to be sorted is very large. This statement is incorrect because internal sorting is only suitable for sorting data that can fit entirely in the main memory. If the number of items to be sorted is very large and exceeds the capacity of the main memory, external sorting must be used instead.
Correct Statements:
The correct statements are:
- Internal sorting: Used when data can fit entirely in the main memory (RAM).
- External sorting: Used when data is too large to fit in the main memory and requires external storage.
- External sorting needs auxiliary storage: External sorting requires additional storage, such as hard disks, to store and manipulate the data.
- Internal sorting does not need auxiliary storage: Internal sorting algorithms operate entirely within the main memory and do not require additional storage.
In conclusion, the false statement is that internal sorting is used if the number of items to be sorted is very large, which is incorrect as external sorting is used in such cases.
