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