Incorrect spelling


Incorrect spelling, explanation: the verb+ing form of the verb choose is written without changing the spelling of the core verb, thus choosing is the spelling that is correct. Chosing is spelled with only one o, which is contrary to the original verb, therefore it is wrong.

Correct spelling


Correct spelling, explanation: choosing is a gerund form of the verb choose, which is spelled with the double vowel o. Pronunciation also points to two double o spelling. This is why choosing is the correct form. The past simple form, chose, may be the reason for the misspelling chosing.
