Interrogative clause

Hi,

I'm sorry for posting a lot of questions today. Could you look at the following sentences and tell me whether the use of prepositions is proper?

ex1)

A: I'm worried whether we'll get there in time.
B: I'm worried about whether we'll get there in time.
C: I'm worried as to whether we'll get there in time.

ex2)

A: I'm not certain where it came from.
B: I'm not certain of where it came from.

My grammar book says that adjectives such as "worried" and "certain" allows the optional inclusion of a preposition when they take an interrogative clause. So I'd like to know if my sentences are all correct.

I'd greatly appreciate your help.
