The answer is option A. Is option C also acceptable?
I agree, because according to the Merriam-Webster dictionary, ‘You need not say so’ dates back to 1921. Therefore it’s use is a bit old-fashioned. Mind you, I don’t think being old-fashioned is wrong. However, I do prefer ‘You don’t need to say anything about it.’
We know that the verb need can be used as an auxiliary (modal) and as a main verb.
When used as an auxiliary, we do not use the particle to.
So, the question can have two answers depending on how you want to treat the verb.
If treated as an auxiliary, Option A will be correct. If as a main verb, Option C will be correct.
American English uses the verb (need) mostly as a DO-verb, so we find Option C as the most common answer.
In English, need say and need not say are modal expressions whereas need to say and do/does not need to say are verbal expressions in the present tense.
To change the subject, here is another odd wording that you don’t hear too often. (Maybe there should be a place to make a list of these.)
For to I went to the store for to buy some bread.
I heard this in a song recently. It’s not just creative writing for song lyrics. I do hear people say this on rare occasions. It’s regional in the US.
Lyrics from If I Needed You by Townes Van Zandt
If I needed you
would you come to me,
would you come to me,
and ease my pain?
If you needed me
I would come to you
I would swim the seas
for to ease your pain
