What does the Greek letter 'Omega' represent in English?

The Greek letter 'Omega' corresponds to the symbol 'Ω' in the Greek alphabet. In the context of translation to English, 'Omega' is used to represent the last letter in the Greek alphabet, similar to how 'Z' is the last letter in the English alphabet. The significance of 'O' in the title is an interesting note, as it is the English pronunciation of 'Omega,' but it does not reflect the symbol itself. Therefore, the most accurate representation in the given choices is 'Ω,' which is the actual symbol for the letter 'Omega'. This distinction is crucial in understanding how Greek letters are represented in both their original form and in English context.
