C Correct answer
Explanation

The getAttribute(String, int) method is the most efficient way to access an attribute when you know its scope because it bypasses scope searching. The int parameter is a scope constant (APPLICATION_SCOPE, SESSION_SCOPE, REQUEST_SCOPE, PAGE_SCOPE) that directly accesses the specified scope. getAttribute(String) without scope parameter searches all scopes sequentially, while findAttribute() also searches scopes. getPageContext() returns the PageContext object itself, not the attribute value.
