In the following question, four other words are provided as alternatives alongside a given word. One of these words cannot be formed using the letters of the given word. Identify that word.

Given word: "FORMATION"

Given: FORMATION

Now, checking options one by one:

Option 1) RATIO → FORMATION → can be formed

Option 2) MINOR → FORMATION → can be formed

Option 3) MAJOR → FORMATION → J is not present, so it cannot be formed

Option 4) TRAIN → FORMATION → can be formed

So, 'MAJOR' cannot be formed by using each letter of the word given below only once.

Hence, the correct answer is "Option 3".
