Questions are often asked by the students when they understand the concept very well and also when they don't understand the concept. In both the circumstances, one thing common is that student has the curiosity and he is trying to understand the concept. Questions help to assess a student's knowledge because his/her level of understanding can be calculated by the type of question a student asks. The teacher will be able to decide whether the student is a proficient or a beginner in that particular concept according to the question asked to him easily.Questions without any doubt provide an opportunity for the students to express themselves because when a teacher completes any concept or lesson a student's mind will be filled with several doubts that he/she wishes to discuss with the teacher. So students asking doubts should always be encouraged by the teacher.Questions also indicate the curiosity of the students towards the topic, as soon as a student gets any urge or doubt he/she will be very curious to clarify that one by their teacher to check that whatever was there in their mind is right or not. Additional InformationPsychomotor skills are demonstrated by physical skills such as movement, speed, hand-eye coordination, etc. This has a zero relation with the questions asked by the student. So the ability to ask questions doesn't evaluate the psychomotor skills of students.Hence, we can conclude that A, B, and C only is the correct answer.
