The italicized word is <em>extremely </em>and the correct answer is intensive.
The word extremely is an adverb, which means that you can rule out <em>noun, adjective, </em>and <em>verb </em>immediately. You can also rule out <em>empty word </em>because <em>extremely </em>has a particular meaning on its own, which means that it cannot be empty. Thus, we are left with one option only - <em />intensive.
