ответ: ...have finished my homework...

Объяснение:

Здесь мы используем present perfect, так как, предположительно, действие завершилось (выполнение д/з) совсем недавно. По правилу в этом случае мы используем Present Perfect.

"Had finished" будет неверно, потому что Past Perfect используется, когда нужно передать, что действие выполнилось до какого-либо другого действия. Например, "I had done my homework before I went for a walk with my friends". Я выполнил домашку до того момента, как пошел погулять с друзьями.
