Vital capacity is the maximum amount of air a person can breathe in after a forced expiration. It includes Tidal Volume (TV), Inspiratory Reserve Volume (IRV), and Expiratory Reserve Volume (ERV).
Ref: NCERT Biology Textbook for Class XI and XII (Zoology section), Chapter: Biology - Zoology portion covering relevant system and function.
Tidal volume is the volume of air inspired or expired during a normal respiratory cycle, approximately 500 mL. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

Residual volume remains in the lungs after forced expiration and cannot be expelled.

Total Lung Capacity (TLC) includes Tidal Volume, Inspiratory Reserve Volume, Expiratory Reserve Volume, and Residual Volume.
Ref: NCERT Class 11 Biology Chapter 14: Breathing and Exchange of Gases Mechanism of Breathing and Respiratory Volumes
Residual volume is the amount of air remaining in the lungs even after a forceful expiration, preventing lung collapse.

Go with C — Remaining after maximum expiration. Within Lung Volumes, Capacities and Regulation, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, Remaining after maximum expiration is the option that correctly names the structure, process, or principle asked for in Lung Volumes, Capacities and Regulation. Holding that picture in mind makes Remaining after maximum expiration feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressur
Ref: Animal physiology is Unit 7 of the CSIR NET Life Science Syllabus, covering core body systems. It accounts for roughly 10% of the total marks in Sections B and C.
