<reasoning>

Analyze correlative conjunctions and subject-verb agreement

• "Both... nor" is grammatically incorrect; "both" pairs with "and", while "neither" pairs with "nor".
• "Neither the corn nor the wheat have been harvested" is incorrect because when singular subjects are joined by "neither... nor", the verb must be singular ("has").
• "Both the corn and the wheat has been harvested" is incorrect because subjects joined by "both... and" are plural and require a plural verb ("have").
• "Both the corn and the wheat have been harvested" is grammatically correct.

Analyze pronoun case in compound objects

• The pronoun in "mixes up [my sister and...]" serves as the object of the phrasal verb "mixes up". Therefore, objective case pronouns must be used.
• "I" is a subjective pronoun, making "I and my sister" and "my sister and I" incorrect in the object position.
• "Myself" is a reflexive pronoun, which is incorrect here because there is no preceding "I" in the clause to reflect back to.
• "Me" is the correct objective pronoun, making "my sister and me" the correct compound object.
