Explanation:

To convert a person's weight from kilograms to pounds, you use the conversion factor that 1 pound is approximately equal to 0.45 kilograms. Given that the person weighs 87 kilograms, we want to find out what their weight would be in pounds.

We can set up the conversion like this:

Now, perform the division:

87 kg / 0.45 kg/lb = 193.33 lb

When we round 193.33 to the nearest whole number, we get 193 pounds (lb), which is option C in the list.
