If you're altruistic, you behave in a ___ way.

A. selfish.
B. self-obsessed.
C. selfless.
D. Self-aware.

Answer is C.

Right.

Selfless

To determine the answer, we need to understand the meaning of the word "altruistic". Altruistic is an adjective that describes the behavior of someone who is concerned for the well-being of others and is willing to help or do good for them, often without expecting anything in return.

Knowing this, we can eliminate options A (selfish) and B (self-obsessed) since they are the opposite of what it means to be altruistic.

Option D (self-aware) is not an accurate response as being self-aware relates to having knowledge or understanding of oneself, which is unrelated to altruism.

Therefore, the correct answer is C (selfless) because being selfless accurately represents the behavior of someone who is altruistic and thinks about the needs and well-being of others before their own.
