\nThe correct answer is D) 120.
\n<\/section>\n
\nThe word COVID has 5 letters: C, O, V, I, D. All five letters are distinct. To find the number of different words that can be formed by using all the letters, we need to find the number of permutations of these 5 distinct letters. The number of permutations of ‘n’ distinct objects is given by n!.
\nIn this case, n = 5.
\nNumber of words = 5! = 5 \u00d7 4 \u00d7 3 \u00d7 2 \u00d7 1.
\n5! = 20 \u00d7 6 \u00d7 1 = 120.
\n<\/section>\n
\nThis is a basic problem involving permutations. If there were repeated letters in the word, the formula would be adjusted by dividing by the factorial of the counts of repeated letters.
