• A. 2
• B. 3
• C. 4
• D. 5

Answer: (B)

The number 0.000367 has three significant figures. In scientific notation, significant figures are counted from the first non-zero digit onward. In this case, the leading zeros to the left of the 367 are not significant—they only serve as placeholders to indicate the position of the decimal point. The first non-zero digit is 3, followed by 6 and 7, which makes a total of three significant figures: 3, 6, and 7. Thus, the correct count of significant figures in the number 0.000367 is three.
