Art can be ____________ because it encourages individuals to express their emotions through a creative outlet, allowing them to process complex feelings, reduce stress,and ____________ self-awareness.

The sentence examines the psychological and emotional advantages of art, highlighting how it aids in self-awareness and the management of difficult emotions. The blanks should be filled with terms that support the therapeutic benefits of art and its role in personal development.

For the first blank, therapeutic (option D) is the best choice, because it conveys the healing and calming nature of art, aligning with ideas like stress reduction and emotional processing. The second blank should have a word that implies "art helps increase self-awareness", so "enhance" is the only option here. Thus, option D is the correct choice. 

The other options are off in meaning or tone. "Pleasing; decrease" downplays the deeper emotional value of art and contradicts the goal of increasing self-awareness. "Acceptable; disturb" introduces a jarring and inappropriate contrast. "Avoidable; mitigate" doesn't make sense in this context—art isn't something to be avoided, and "mitigate self-awareness" is illogical. Only "therapeutic; enhance" clearly and accurately completes the sentence in a meaningful way.
