The correct answer is [4] Each of the teachers teach in a different way.
Explanation:
In grammar, indefinite-pronouns are words such as all, every, many, each, someone, etc. that refer to a subject indefinitely. Additionally, depending on the indefinite pronoun this is considered as singular or plural and therefore should be followed by a singular or plural form to show pronoun verb agreement. For example the pronouns each, every, somebody are singular while the pronouns many, all or both are plural. According to this, the sentence with an indefinite-pronoun verb agreement is "Each of the teachers teach in a different way" because the indefinite pronoun should be followed by the singular form "teaches" rather than the plural form "teach".
