Answer:
"The Children Choose Only The Best Stones For What Is About To Take Place"
Step-by-step explanation:
The question is asking what informinformation is "REVEALED" so this is just a classic bait and switch, someone may choose to go with B. but techtechnically that is not directly said through this passage, though it may be true- there is just not enough information given. D. should be correct because it is directly stated in the passage that the children only picked up the smoothest and roundest stones, which you can infer must be the 'best' stones for whatever is going to take place next.
