Step-by-Step Solution

Solution:

Step 1: Understand PHP's behavior with non-numeric strings in math
PHP tries to convert '10 apples' to number; it extracts leading number 10 but may raise a warning if strict error reporting is on.
Step 2: Identify the fix
To avoid warnings, explicitly extract the numeric part (e.g., using intval) before addition.
Final Answer:
Warning due to non-numeric string; fix by extracting number before addition. -> Option B
Quick Check:
Non-numeric strings cause warnings in math = C [OK]

Quick Trick: Extract numbers from strings before math to avoid warnings [OK]
