@9thEagle -- Sorry about that, I thought that the FIDE World Chess Championship was the official one while the PCA World Chess Championship was unofficial. :/
Anyways, I have confirmed that (c) from the previous round was indeed true based on Wikipedia, so whoever answered that statement will be given a point too. Sorry for the trouble.
d is true.
But I don't think (F) is true :( because the king can either fork up to 3 pieces (assuming "fork" means it must make a move to attack a piece it wasn't' previously attacking"), or 7 pieces, if we take the definition of "fork" to simply mean all the pieces which are simultaneously attacked. Even if we consider a fork number to be the number of pieces that can legally be captured, can the king can fork a maxiumum of 4 (see below for my best solution, although perhaps a better one may be found).
