Which of the following is mis-spelt ?

Question

Accepted Answer

The correct answer is Option 3 because the word "Audaciouss" is misspelled. The correct spelling is "Audacious" with only one 's' at the end.

Here's why the other options are incorrect:

*   **Option 1: Psychology** - This word is spelled correctly. It refers to the scientific study of the human mind and its functions.

*   **Option 2: Colourful** - This word is spelled correctly. It means full of color or having many bright colors. Note that "colorful" is also a correct spelling, but "colourful" is acceptable, especially in British English.

*   **Option 4: Thermometer** - This word is spelled correctly. It is an instrument used for measuring temperature.

Therefore, only "Audaciouss" contains a misspelling, making Option 3 the correct answer.
