Option D is correct. Since there are some if statements which do not have any else part and they cannot be converted into ?: So 3 conditions are fulfilled but first condition is not fulfilled.

Friends here only only if - else can be replaced by ternary operator but not more than one it is wrong so there he specified more than one if-else.

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.

We can use ?: for nested if else statements too. Like if (x>5? (x>10?x=1:x=2) :x=3).
What does it mean by multiple if else statements?

@Madhu.
You are right for this case but many case like (return X) in if condition so ?: is not allowed if condition only.

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

Can we multiple else statements?
If so which else statement will be executed in case failure of if statement?

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

'?:' can be used instead of single if else statement and you can't use it in multiple if else statements..:)

We can't use return statements in ?: whereas we can use it in if else blocks.
So option D is true.
