The correct option, "Either Ekaette or you are to go," adheres to the principle of subject-verb agreement The concord rule dictates that when "either" is used in a structure where it is followed by "or," the verb agrees with the nearer subject. In this case, the subjects are "Ekaette" and "you," and "you" is closer to the verb "are." Therefore, the form "are" is the correct choice to maintain proper subject-verb agreement.
