Step 1: List the correct spelling of each target word.
The intended correct words are superintendent, sleeve, allotted, and dissipate.
Step 2: Compare each option letter by letter.
superintendant swaps -ent for -ant, which is wrong. sleve is missing a letter compared to sleeve. alloted uses a single t instead of the double t in allotted. dissipate matches its correct form exactly, letter for letter.
Step 3: Confirm the one correct match.
Since only dissipate matches its standard spelling without any change, it is the answer.
Final Answer:
dissipate is spelled correctly. $$ \boxed{\text{dissipate, option D}} $$
