Solution

The correct option is B Exactly five mobile phones feature a music player
MobileModelsDigitalCameraMusicPlayerOfficeDocumentViewerTVWXYZ
The options for 4 models are clear. Further Z has a music player as T has fewer options as compared to Z, i.e., Z has 2 options as T will have 1 option. So one option has to be music player for Z as only one option is common with V who has digital camera and office Document viewer. The one option T has can be a music player so only a maximum of 4 mobiles have a feature of music player.
