Correct answer
C. (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
Step-by-step solution
Zero error of vernier calipers arises from built-in defects of the measuring instrument, hence it is an instrumental error (A-III). Ignoring the buoyancy of air while weighing a body is a flaw in the experimental procedure, which is an imperfection in experimental technique (B-I). Parallax in reading a scale occurs due to an individual's improper setting of the apparatus or carelessness in taking observations, making it a personal error (C-IV). Unpredictable mechanical vibrations cause irregular fluctuations in the
