Explanation:

- Each letter is assigned an odd numerical value. Starting with A = 1, B = 3, C = 5, D = 7, E = 9, and so forth.

- For the word "RADICAL" the letters translate to:

- R = 35

- A = 1

- D = 7

- I = 17

- C = 5

- A = 1

- L = 23

- Add these values: 35 + 1 + 7 + 17 + 5 + 1 + 23 = 89

- Option 3: 89 is correct.
