The logic for (b) and (c) is wrong: the king wouldn’t be in an Isardam-illegal position, the king would place itself in check.

You are right, the definition of Isardam actually does not forbid king-to-king checks; therefore, the reason why Black cannot capture in b) and c) is indeed because he would then put himself in (the reactivated) self-check. The point of the problem remains the same though.

Thank you for your comment and all the best in 2019!
