Order of selection matters in Permutations while it does not matters in combination. So for the given problem we have to you combinations.

We are to find the combinations of 26 teachers taken 6 at a time i.e. we are to find 26C6.

26C6 = 230230

So, 23023 to select the 6 teachers for training session.

Therefore, the correct answer is option B
