Answer:
1) B) The ocean has many beautiful things to offer, but they are best left untouched by humans.
2) D) “it held wealth / beyond measure / she left it behind for the ocean to keep.” ( Lines 17-19)
3) D) It wasn’t hers to take.
Step-by-step explanation:
The author describes the great value of the treasure and how it was just lying under the ocean unexplored by humans. The diver is a human, and despite seeing clearly the immense values of this treasure, decided to leave it in the ocean. The phrase "and though she could see it held wealth beyond measure she left it behind for the ocean to keep." explains this point.
The diver left this treasure behind because she was just a diver, it was not her prerogative to go search for underwater treasures. Nowhere in the passage suggests that the treasure's wealth is limited to the ocean and useless on the land. It's wealth was even described to be beyond measure.
It was not written that she made an attempt to carry the treasure but could not due to difficulty.
