n the old days, the Nielsen ratings of TV-watching habits would ask people to fill out a card indicating how much TV they watched and which shows they watched. Why did they get different results when they used electronic monitoring devices instead?

My options are as follows and I think it is D, just looking for some input.
 People might say they watch less TV than they do because some people consider it a lazy activity.
       People might not be truthful about the shows they actually watch.
       Some people leave the TV on when they are out of the house, so they aren’t actually watching the shows that the electronic device is monitoring.
       All of the above.
