Incorrect spelling, explanation: -tion sound in English is a tricky one, especially for non-native speakers. In the case of occasion, there is no -tion ending because of the word’s Latin origins – occasionem. In accordance with the original, the correct English spelling is occasion (double c, one s), not ocation.

Correct spelling, explanation: this form is correct as its origin is Latin occasionem (nominative occasio). In the original word, you can see similar spelling as in later English occasion – double c and one s. This points to occasion as the correct form and ocation as a misspelling.
