The correct spelling of the word is "Almighty", written as one word with a single "l" in the first syllable and a single "m" before "ighty".
- Option A, "Almighty": This spelling is correct. It has one "l" and follows the standard form of the word used for "all powerful".
- Option B, "Allmighty": This adds an extra "l", which is a common spelling mistake. The correct word never doubles the "l".
- Option C, "Almity": This drops the "gh" from the middle of the word, which changes it into a wrong spelling with no meaning.
- Option D, "Almighty": This option repeats the same correct spelling as option A. Since only one answer can be marked, the given key selects option A as the correct one.
The correct choice is option A, "Almighty".
