B:150g The reason why is because, when using units! I usually do a little trick I call King Henry.
King Henry Doesn't Usually Drink Chocolate Milk. So, Usually means grams and King is kilograms..Finally you do multiplication and that is moving grams up by 100 and that is how you get an answer of 150g.
Your answer would be 1500g since there are 1000 grams in a kilogram.
Brief Explanation.
For every 1 kilogram there's 1000 grams so if you were to have 1.5 kilograms you'd have 1,500 grams. 500 is half of 1000 so if you have a .5 you'd have 500 grams which you would then add 500 to 1000 which would result in your answer of 1500
