That’s right but if you add ionosphere which is an obvious layer then the answer would be 6 layers. Like the troposphere, stratosphere, mesosphere, thermosphere, exosphere are major five and ionosphere makes them six. However, the answer was 4 layers if they would have asked the primary layers of atmosphere.
