The correct answer is C. Eratic.
The other options, A. Envelop, B. Enthuse, and D. Emigrant, are all spelled correctly.
- Envelop is a verb meaning to cover or enclose something completely.
- Enthuse is a verb meaning to fill someone with enthusiasm.
- Emigrant is a noun meaning someone who leaves their country to settle permanently in another.
The word "erratic" is spelled correctly, but it is not the correct answer to the question because it is not a word that means "to leave one's country to settle permanently in another."
