120

- The word ‘ARISE’ consists of 5 different letters.

- The number of ways to arrange these letters is given by calculating the factorial of the number of letters.

- Therefore, we calculate 5! (5 factorial), which is 5 × 4 × 3 × 2 × 1.

- This results in 120 different ways to arrange the letters.

Here's the evaluation of the options:

- Option 1: 90 - Incorrect, as 5! is not 90.

- Option 2: 60 - Incorrect, because 5! results in a higher number.

- Option 3: 180 - Incorrect, as it surpasses the factorial result of 5 letters.

- Option 4: 120 - Correct, as 5! equals 120.
