A:
Yes it will. It comes with an adapter. Therefore if the memory card is to small you simply place it in the adapter and its bigger and ready to function.
There are several GBs to choose from but if you use your tablet and save games and other data you will certainly benefit from the 64GB or higher. You wont be disappointed for purchasing it.
Once you have it go ahead and install it. Don't wait until you start getting messages about memory running low. It's a horrid feeling to loose information if you have to restart your tablet to get your memory card activated.
