The correct answer is A. Estimation.
An appraisal is an estimate of the value of something. It can be used to determine the worth
of a property, a piece of art, or even a person’s performance at work.Praise is a statement of admiration or approval. It is often used to express appreciation for someone’s good work or behavior.
Approval is a favorable opinion or judgment. It is often given to something that is considered to be good or acceptable.
Investigation is a process of gathering information in order to find out the truth about something. It is often used to solve a crime or to determine the cause of an accident.
In this case, the word “appraisal” is most closely related to the word “estimation.” Both words refer to the process of determining the value of something. However, an appraisal is typically more formal and objective than an estimation. An appraisal is often conducted by a professional, such as a real estate appraiser or a financial analyst. An estimation, on the other hand, can be done by anyone who has the necessary knowledge and experience.
