Consider the following code block:

switch( grade ) {

case 5:

case 4:

a = 1;

b = 2;

break;

case 3:

a = 5;

break;

default:

a = 2;

break;

}

Which of the following if statements is equivalent to this switch statement?

ift grade == 4){ a = 1; b = 2; } else ift grade ==3){ a = 5;} else { a = 2:} if (grade == 4 && grade == 5) { a = 1;b = 2; } else if (grade == 3) (a - 5;} else {a = 2;} if (grade == 4 || grade == 5){ a = 1; b = 2; } else if (grade == 3){a = 5;} else { a = 2;} ift grade !=5){ ift grade == 4){ O a = 1;b = 2; } else ift grade == 3){ a = 5:) else {a = 2;} } O None of the above
