Connective prepositions before, after, when, while, as soon as, etc. may be added to a clause to express that a second activity occurs earlier than, later than or at the same time as the activity in the main clause.
If the verb in the main clause is present tense, the verb in clause following the preposition is also present.
After we finish our homework, we go for a walk. (later then, as we
usually do)
Connective prepositions may also be added to a clause with a future tense verb expression such as will or (be) going to. In this case, the verb in the clause following the connective preposition does not change tense. It remains in present tense form.
After we finish our homework, we'll go for a walk. (later then, today)
So, the correct choice will be
It will be delivered after it is inspected. (first it will be inspected then delivered)
The difference between variants A, B, and C is that only variant A is grammatically correct.
The two are very similar and could easily be interpreted to mean the same thing, but there are subtle differences in what the speaker might have meant:
With I'm never having the speaker might be resolving to never have a beard, because he really doesn't want one. (This is progressive tone; we hear the future lack of a beard as something the speaker will maintain by force of will.)
With I'll never have the speaker might have concluded that he (she?) is permanently unable to grow a beard, either physically (perhaps genetically, or perhaps a skin disease), or perhaps a rich aunt's will prohibits bearded relatives from inheriting. (This implies a pefective aspect; we hear the future lack of a beard as something out of the speaker's control).
It's a little farfetched in the specific case of beards: you really have to strain to think of a plausible situation for the "I'll never have" version.
But the difference is much easier to see between "I'm never having a Mercedes" (from an Audi lover) and "I'll never have a Mercedes" (sigh, I'll never be able to afford one).

Actually, in your case, what you want is a slightly different sentence:
or
or, my preference would be:
The future perfect tense (i.e. "will have become") is used for things in the future that will have been completed, but it does not matter when they were completed. For example:
The reason why you don't need the future perfect in your sentence (or any future tense) may become clearer with these examples:
The expression "looking forward to" usually expects an "-ing" form, as in "I'm looking forward to seeing you again." You can add words after "looking forward to" and avoid the 'ing, as in:
So you can say "I'm looking forward to when I'm good at English", or use an -ing form and say "I'm looking forward to becoming good at English".
Finally, "with great clarity" means something a bit different - it's not so much about speaking clearly, but about being understandable:
