Step-by-Step Solution

Solution:

Step 1: Understand variable scope and case sensitivity
In Ruby, local variables start with lowercase letters, constants start with uppercase letters.
Step 2: Identify which variable is printed
The method prints score (lowercase), which is 7. Score (uppercase) is a constant and not used in puts.
Final Answer:
7 -> Option B
Quick Check:
Local variable printed, not constant [OK]

Quick Trick: Local vars are case-sensitive and distinct from constants [OK]
