Well, I'm going to stick my neck out, and say that if you were my student, I would be encouraging you to explore a wider choice of repertoire before focusing on the next grade immediately.
However - since you ask! ...
All the A pieces are good. At a quick glance, the Vanhal doesn't appear to present any particular technical difficulties, and I'd be unlikely to discourage any student of mine from choosing it.
The B group - not bad. I think 1 is probably the trickiest - you can tell from the score it needs very accurate and nimble fingerwork. Might be rewarding to learn though. 3 certainly looks straightforward, It happens to be in the same key as A3, and I have an instinctive dislike of preparing / presenting two in the same key in a three piece programme. I must stress that there is actually no problem in doing this - it's simply a personal choice and something I will try to avoid if I can. I feel it's worth broadening a student's experience if possible, and variety is more enjoyable. It's not generally regarded as important, by the way. The alternative Tchaikovsky Mazurka is a good piece if you want another option.
Group C - I more or less agree with you. Sorry - that's no help at all! I dislike C1: the other two are less dull.
