Given this PHP code, what will be the output?

 $score = 85;
 switch (true) {
   case ($score >= 90):
     echo 'Grade A';
     break;
   case ($score >= 80):
     echo 'Grade B';

   case ($score >= 70):
     echo 'Grade C';
     break;
   default:
     echo 'Fail';
 }

AGrade A

BGrade B

CGrade C

DFail

Step-by-Step Solution

Solution:

Step 1: Understand switch(true) usage
The switch compares true to each case condition result.
Step 2: Evaluate each case condition
$score is 85, so ($score >= 90) is false, ($score >= 80) is true, so it matches case 2 and prints 'Grade B'.
Final Answer:
Grade B -> Option B
Quick Check:
Switch(true) matches first true case = Grade B [OK]

Quick Trick: Use switch(true) to check conditions in order [OK]

Common Mistakes:

Expecting switch to compare values directly
Not understanding switch(true) trick
Missing break causing fall-through
