Strassen's Matrix Multiplication Algorithm - Usage

Which describes the best usage of Strassen's matrix multiplication algorithms relative to the traditional algorithm (e.g. taught in Linear Algebra) where the matrices to be multiplied are n x n?

A) Use the traditional algorithm for all sizes of n

B) Use Strassen's algorithm for all sizes of n

C) Use Strassen's algorithm for small n and the traditional algorithm for large n

D) Use Strassen's algorithm for large n and the traditional algorithm for small n

E) Use Strassen's algorithm for large n but when the sub-problems get small switch to the traditional algorithm
