What role does asynchronous or deferred loading of Bootstrap JavaScript files play in page load efficiency?
- Improves page load efficiency by loading scripts in parallel
- Degrades page load efficiency by delaying script execution

Explain how event delegation is utilized in Bootstrap Tooltips on dynamically created elements.
- Utilizing the data-toggle attribute on the dynamically created elements
- Binding the tooltip events to a static parent container
- Directly attaching tooltip events to each dynamic element
