Step-by-Step Solution

Solution:

Step 1: Analyze variable declaration and assignment
count is declared with var, so it can be changed. Initially, it is 5, then reassigned to 10.
Step 2: Understand print output
The print statement outputs the current value of count, which is 10 after reassignment.
Final Answer:
10 -> Option C
Quick Check:
var allows reassignment, so output is 10 [OK]

Quick Trick: var allows change, so print latest value [OK]
