return x>y?1:0;
It will work.
I think question is misprinted, first one is correct
Tell me a single example which cannot be converted.

I think all four options are correct. because we can replace every if-else with ?: even nested ones also.
eg. if(a==5){
if(b==5){
printf("%d",b);
}
else{
printf("%d",b+1);
}
}
else{
printf("%d',a);
}
It can be replaced by.
(a==5)?(b==5?printf("%d",b):printf("%d",b+1)):printf("%d',a);
eg. if(a==5){
if(b==5){
printf("%d",b);
}
else{
printf("%d",b+1);
}
}
else{
printf("%d',a);
}
It can be replaced by.
(a==5)?(b==5?printf("%d",b):printf("%d",b+1)):printf("%d',a);

I disagree with the answer because one can write nested ternary operators equating nested if else statements.

Actually, ?: this indicates that conditional operator,we use this ?: as an alternative for if-else functions limitedly.
