Though 'E' looks good to me too, let me take different stand...
'C' says, slots will be available in blocks of more than 30sec, last fall it was less than 30secs. So if block size is increased & there is also increase in advt. cost, it's balanced...
What is the OA? & OE?
But that doesn't necessarily mean that advertisers will continue to profit from television advertising. It would only increase the cost of advertising. No info can be gathered on profits realised by as companies.
Hence "e". Since if more people are watching there are chances that you will increase revenue by TV ads.
A - Again rejected for same reason as C
B and D - Out of scope.
Anyway, OA and OE?
