Helping someone in need corresponds to a form of empathy and altruism, which is based on the moral emotions we feel when we see a person in a situation that we have the ability to help.
According to the theory of social exchange, altruism only exists if the benefits to the helper outweigh the cost, so supported by this theory, the letter b is correct, and Joseph will help the man if the costs of helping are small.

<em>I personally communicate my thoughts by saying how I feel to people around me with all honestly. </em>
<em>I am a very open and honest person. I always say how I see things and how I feel about a person, event or certain matters. But I have to be careful on the choice of words that I will say because not all people will be happy to hear my thoughts. I learned to be more sensitive with exercising my rights to be honest and open to others. I also approach people in the right time and venue to make them comfortable in awful situations and relax in embarrassing situations.</em>
