Question

What is the best case time complexity of radix sort algorithm?

The correct answer is

Ω(nk)

Radix Sort Best Case Analysis The question asks for the best-case time complexity in terms of \Omega notation (lower bound). Therefore, the total number of operations will still be proportional to k × (n+b). This means the best-case, average-case, and worst-case time complexities are all O(nk), and thus the lower bound (\Omega) is also \Omega(nk). Therefore, the correct answer is Ω(nk).
