At a certain high school students receive letter grades based on the following scale: 93 or above is an A, 84 to 92 is a B, 75 to 83 is a C, and below 75 is an F. Which of the following code segments will assign the correct string to grade for a given integer score? I. if (score >= 93) grade = "A"; if (score >= 84 && score <=92) grade = "B"; if (score >=75 && score <= 83) grade = "C"; if (score < 75) grade = "F"; II. if (score >= 93) grade = "A"; %3D if (score >= 84) grade = "B"; %3D if (score >=75) grade = "C"; if (score < 75) grade = "F"; III. if (score >= 93) grade = "A"; else if (score >= 84) grade = "B"; else if (score >=75) grade = "C"; else grade = "F";

Question

Why is choice I not correct? It works fine unless "score" is a double value.

At a certain high school students receive letter grades based on the following scale: 93 or
above is an A, 84 to 92 is a B, 75 to 83 is a C, and below 75 is an F. Which of the following
code segments will assign the correct string to grade for a given integer score?
I. if (score >= 93)
grade = "A";
if (score >= 84 && score <=92)
grade = "B";
if (score >=75 && score <= 83)
grade = "C";
if (score < 75)
grade = "F";
II. if (score >= 93)
grade = "A";
if (score >= 84)
grade = "B";
%3D
if (score >=75)
grade = "C";
if (score < 75)

III. if (score
>= 93)
grade = "A";
else if (score >= 84)
grade = "B";
else if (score >=75)
grade = "C";
else
grade = "F";
