Solution
The correct option is B 24 Carat
24 carat gold is 99.9% gold and is very soft. This is why it's not preferred to make jewellery.
The 22 carat gold is used for making jewellery even though it's not pure. This is because it's harder and long lasting. Small amounts of metals such as copper, silver, nickel, zinc are added to make it harder.
