Step-by-Step Solution
Solution:
Step 1: Understand URL resolution with base
The relative path 'page.html' is resolved relative to the base 'https://example.com/folder/'.Step 2: Combine base and relative path
Since base ends with '/', the relative path appends to it, resulting in 'https://example.com/folder/page.html'.Final Answer:
https://example.com/folder/page.html -> Option DQuick Check:
Relative path appended to base folder = D [OK]
Quick Trick: Base URL ending with '/' appends relative path directly [OK]
Common Mistakes:
- Ignoring trailing slash in base URL
- Assuming relative path replaces base path
