Question

can anyone please modify the lifelines part of this Java code?

1. when the user enters "ff", (50:50 lifeline), 2 of the 4 choices in the question currently being answered are removed, leaving the user with only 2 choices to choose from.. however currently in this code, it automatically removes choices c and d even if the answer is in either a or b.. so I need a modification that will not remove the correct choice but rather remove 2 of the wrong choices

2. the lifelines can only be used by the player only once per round (easy, average, hard) then the player must be told that he has already used the lifeline for the current level.. however currently in this code, the lifelines can be used thrice for the WHOLE game and not once per round..

so I need the modifications please.. thanks so much! by the way I am from the Philippines that is why the currency of the game is in Philippine pesos
