The correct answer is: A. Communication, assertiveness and punctuality.
Communication is the foundation of trust. When people communicate effectively, they are able to share their thoughts and feelings in a way that is clear and respectful. This allows them to build understanding and rapport, which are essential for trust.
Assertiveness is also important for trust. When people are assertive, they are able to stand up for themselves and their beliefs in a way that is respectful of others. This shows that they are confident and capable, which are qualities that people tend to trust.
Punctuality is another important element of trust. When people are punctual, they show that they are reliable and dependable. This is important because it builds trust and makes people feel comfortable working with them.
Attraction, politeness, and affirmation are all important qualities, but they are not as essential for trust as communication, assertiveness, and punctuality. Attraction can lead to trust, but it is not a guarantee. Politeness is important for building relationships, but it does not necessarily lead to trust. Affirmation can make people feel good, but it does not necessarily make them trust you.
In conclusion, the three elements that promote trust are communication, assertiveness, and punctuality. These qualities are essential for building strong relationships and creating a foundation of trust.
