Answer: PowerPoint has a free, built-in service for broadcasting online.
Explanation:
The statement that's true about the broadcast of a slideshow online is that PowerPoint has a free, built-in service for broadcasting online.
Option 1 is wrong as all transitions are not properly displayed to the audience when broadcasting online.
Option 2 is wrong as broadcasting as slideshow online is an option for most PowerPoint users.
Option 3 is wrong because when broadcasting online, third party desktop sharing software isn't necessarily an option and it isn't a must that it must be used.
Therefore, the correct option is 4.
