To find the speed of the object, you can use the formula:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
In this case, the object travels a distance of 10 centimeters in a time of 2 seconds.
\[ \text{Speed} = \frac{10 \text{ cm}}{2 \text{ sec}} = 5 \text{ cm/sec} \]
Since 5 cm/sec is not among the response options you've listed, please double-check the details. According to the calculation, the speed is 5 cm/sec. If you need to match it with the options provided, note that none of them are correct.
