To convert 0.00051 to scientific notation, we move the decimal point 4 places to the right to get 5.1, and then multiply by 10 raised to the exponent that tells us how many places we moved the decimal point. In this case, we moved the decimal point 4 places to the right, so the exponent is -4. Thus, 0.00051 in scientific notation is 5.1 × 10⁻⁴. Choice C is the only one that matches this.
