Which of the following is false? A. LSD radix sort is an integer sorting algorithm B. LSD radix sort is a comparison sorting algorithm C. LSD radix sort is a distribution sort D. LSD radix sort uses bucket sort

Option b is false

Explanation:

Radix sort is not a comparative sorting algorithm. It creates and distributes element into buckets and according to their radix thereby avoiding comparisons. If elements have significant digits that are more than one, the bucketing would be redone for each digit. While it is doing this, ordering of former step is preserved till every digit has been attended to. It can also be called the bucket or digital sort.

LSD radix starts from the least to the digit which is most significant.
