b.To serve as a nailing base for baseboard trim
c.To provide the finished ceiling line

Giải thích
The double top plate laps at corners and intersections to tie wall segments into a continuous unit and distribute point and uniform loads from framing above. It is not for baseboard nailing, ceiling finish, or sprinkler mounting, which are unrelated to its load-transfer purpose.
