Verified step by step guidance

1. Identify the conversion factor between grams and kilograms. Since 1 kilogram equals 1000 grams, we use the relationship: \$1\ \text{kg} = 1000\ \text{g}$.
2. Set up the conversion by dividing the given mass in grams by 1000 to convert it to kilograms: \(\text{mass in kg} = \frac{\text{mass in g}}{1000}\).
3. Substitute the given value of 12,980 grams into the equation: \(\text{mass in kg} = \frac{12980}{1000}\).
4. Perform the division to find the mass in kilograms (do not calculate the final number here, just set up the expression).
5. Interpret the result to select the correct answer from the options provided, noting that dividing by 1000 moves the decimal point three places to the left.
