4Consider the following conditional code, which returns a Boolean value:
if ((x>25) && (y>100))
return 'false';
else if ((x<=25) && (y<=100))
return 'true';
else if ((x>25) && (y<=100))
return 'false';
else
return 'true';
Simplify it by filling in the following blank with a single Boolean expression without changing the behavior of the conditional code.
if (____________)
return 'true';
else
return 'false';

- B) x≤25
- C) y>100
- D) y≤100
