Choose the correct option to fill in the blank:-

The teacher will _____ the student's performance before giving the final grades.

Appraise

The correct answer is Option (2) → Appraise

The sentence is about the teacher evaluating the student's performance before giving grades. Appraise means to assess or evaluate the value or quality of something – correct in this context. 

• Approx is an abbreviation for "approximately" and does not fit grammatically.

• Apprise means to inform or tell someone.

• Praise means to express admiration or approval. While a teacher might praise a student, "appraise" is the more formal and accurate word for the process of evaluating performance before giving a grade.
