Conditional operator can be used for multiple if-else statements..
ex:
using if-else:-
if(x!=40)
if(x<40)
salary=4*x+100;
else
salary=4.5*x+150;
else
salary=300;
Using conditional operator:-
salary=(x!=40)?((x<40)?(4*x+100):(4.5*x+150)):300;
ex:
using if-else:-
if(x!=40)
if(x<40)
salary=4*x+100;
else
salary=4.5*x+150;
else
salary=300;
Using conditional operator:-
salary=(x!=40)?((x<40)?(4*x+100):(4.5*x+150)):300;

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

We can replace an if-else structure with a ternary operator. Isn't it so?

Simple in under one if statement we can declare many if and else satements.

Option 3. Multiple statements in an if block are allowed - is also correct, because we can execute multiple statements against true value of if (condition) by placing the statements within { and }.
So all the options are correct.
So all the options are correct.
