I feel like either C or D works, but in that context I'd choose D.
I understand this question to mean "an action that is perceived or sensed rather than performed" so, for example a feeling or perception rather than an action - some examples are
-to want
-to love
-to need
-to wist
-to dislike
-to experience
-to perceive
-to feel
-to fear
D include life skills and experiences, i believe this is the answer
