For this question, we are supposed to find the word whose underlined part has a different sound from the others. In all words, the letter "f" is underlined. So, the one that has a different sound is:
A. Of
The same letter can represent different sounds when used in different words. For example, the letter "f" in "coffee", "leaf", and "fault" has a typical "f" sound.
However, that is not the case with the letter "f" in the word "of". Here, it has a "v" sound. Therefore, we can say the letter "f" in the word "of" has a different sound than in the other words.
With that in mind, we can choose option A as the one containing the word with a different sound.
