Incorrect spelling, explanation: submition is probably mistaken with word submit, but the correct form is submission. This is due to the fact, that submit is from Latin submittere and submission from submissionem. Thus submission is correct.

Correct spelling, explanation: submission originates in Latin submissionem, and due to this it is the correct form. Although ending -tion is pronounced similarly to -sion, Latin origins point to submission. Therefore submition (which may be a misspelling due to the word submit) is incorrect.

Definition of submission:
noun, an act of submitting (for example to authority, or: for consideration) or something that is submitted
Submission day is tomorrow so you better hurry up with filling out this form.
The wrestler felt defeated and signaled his submission.
