To find out how many words can be formed out of the letters of the word "POST," we can use the concept of permutations.

Step 1: Count the number of letters in the word "POST." In this case, there are 4 letters.

Step 2: Since all the letters are distinct, we can use the formula for permutations of distinct objects. The formula is given by n!, where n is the number of distinct objects.

Step 3: Substitute the value of n into the formula. In this case, n = 4. So, the number of permutations is 4!.

Step 4: Calculate 4! = 4 x 3 x 2 x 1 = 24.

Therefore, there are 24 different words that can be formed out of the letters of the word "POST."

So, the correct answer is D. None of these.
