The code segment makes use of conditional statements.
Conditional statements in programming are used to make decisions
The code segment in C++ is as follows
if (score > 90) {
grade = 'A';
}
else if (score >= 80 && score < =90) {
grade = 'B';
}
else {
grade = 'C';
}
The above code segments take the score, make comparison, and then determine the appropriate letter grade.

II and III
Explanation:If it is the test i think it is
I is incorrect because it is saying that automatically it is set as C but if the score is over 90 then you get an A if it's anything else then it's a B. This is false because then your outcome will never be C. It would only be A or B.
II is correct because it starts off by saying that if the score is greater than 90 then you'll get an A if else then if your score is equal to or greater or equal to than 80 then you get B and then if anything else then it's a C. This incoorporates everything.
III is also true because it start off by saying if anything is below an 80 then you automatically get a C. If it's anything over than 80 then if it's equal to or less than 90 then you get a b and if it's anything else then you get an A. This also checks out which means it's true.
So the answer is II and III
