Answer:

B) 3 grams

Explanation:

The half-life for U-238, based on the graph, is 4.5 billion years. This is determined by going to the 50% mark on the graph and following it down to the horizontal axis. So, if you start with a 6 gram sample, after 4.5 billion years, half of it would remain, or 3 grams.
