N which one of the following sentences is a word misspelled? A. Spanish isn't a foreign language if you're Mexican. B. Niether Mike nor Marvin believed in Superman. C. I spend my leisure time reading books. D. Laticia weighed herself on the bathroom scale.

Niether is misspelled. It should be neither.

The correct answer is B. Niether Mike nor Marvin believed in Superman.

Based on these sentences, I can see that you are working on how to spell letters I and E next to each other. You've probably learned the rule 'I before E except after C,' as in believe, fierce, die, etc., however, you can see that this is not always the case, as in the options above. Neither is spelled with E before I, not the other way round.
