Solve the problem.What conditions, when present, are sufficient to conclude that a function f(x) has a limit as x approaches some value of a?
A. f(a) exists, the limit of 
as 
from the left exists, and the limit of 
as 
from the right exists.
B. The limit of 
as 
from the left exists, the limit of 
as 
from the right exists, and these two limits are the same.
C. Either the limit of 
as 
from the left exists or the limit of 
as 
from the right exists
D. The limit of 
as 
from the left exists, the limit of 
as 
from the right exists, and at least one of these limits is the same as f(a).
