Use the rounding method to approximate 846.31 as required. The error in the following four results is ()
A. 846.3 (keep four significant digits) B. 846 (keep three significant digits) C. 800 (keep one significant digit) d. 8.5 × 102 (keep two significant digits)


A. 846.31 ≈ 846.3 (keep four significant numbers), so this option is correct; B, 846.31 ≈ 846 (keep three significant numbers), so this option is correct; C, 846.31 ≈ 8 × 102 (keep one significant number), so this option is wrong; D, 846.31 ≈ 8.5 × 102 (keep two significant numbers), so this option is correct; so select C
