The correct answer is: A. One’s promise should be kept.
A promise is a declaration or assurance that one will do or refrain from doing something. When someone makes a promise, they are essentially saying that they will keep their word. This is important because it helps to build trust and relationships. When people know that they can rely on others to keep their promises, it creates a sense of security and stability.
There are many reasons why it is important to keep one’s promises. First, it shows that you are a person of integrity. When you keep your promises, you are demonstrating that you are someone who can be trusted. This is important in all areas of life, from personal relationships to professional interactions.
Second, keeping your promises helps to build trust. When people know that you will keep your word, they are more likely to trust you in the future. This can be helpful in all sorts of situations, from getting a loan to getting a job.
Third, keeping your promises helps to maintain relationships. When you break a promise, you are essentially saying that you do not care about the other person or the relationship. This can damage trust and lead to conflict.
Finally, keeping your promises simply makes you a better person. When you do what you say you are going to do, you are demonstrating that you are someone who is reliable and trustworthy. This is a quality that everyone should strive for.
The other options are incorrect because they do not accurately reflect the importance of keeping one’s promises. Option B, “One’s promise has to be kept,” implies that keeping a promise is a requirement or obligation. This is not always the case. There may be times when it is impossible or impractical to keep a promise. In these cases, it is important to be honest and upfront with the other person about why you cannot keep your word.
Option C, “A promise should be keeping,” is grammatically incorrect. The correct phrase is “A promise should be kept.”
Option D, “A promise should be kept,” is the same as option A, but it is not as concise.
