Why was the solid rocket boosters of the Challenger designed in four segments requiring o'rings instead of just one piece?

Is four sections a design advantage?

The SRBs weren't manufactured in Florida, so they had to be transported to Cape Canaveral. Doing so as a single piece would not have been possible. 

They could have been manufactured nearby but the shuttle was designed to be able to be launched from California as well as Florida, and setting up two manufacturing sites apparently wasn't in the cards.

Also, having the SRBs in multiple segments made manufacturing easier and it also eased post-flight inspection and refit. 

And in the end, the SRBs performed very well, except for the times (and that's meant to be plural) when NASA launched in unsafe atmospheric conditions. 

(Only one SRB failed during launch. But previous cold weather launches had shown serious damage to the o-rings.)
