Hello!
One kilogram is about 2.2 pounds. Let's convert below.
4.9(2.2)=10.78
One kilogram is about 1.5 stones, but as that is less than 2.2, it won't get us any closer to 11.
A kilogram would be way more than 11 teaspoons, along with 11 ounces.
Therefore, our closest answer is A) Pounds.
I hope this helps!
