The correct answer is B. The percentage of crabs with large claws would increase.

Explanation:

Crabs with large claws have more chances to survive and reproduce; this biological advantage will make most of these crabs to successfully reproduce through generations and pass this feature to their offspring. On the opposite, crabs with smaller pincers do not have this reproductive or survival advantage, this implies many crabs with small pincers will not survive a long time or will not reproduce, and therefore this trait will not past to their offspring. Moreover, this situation will cause after many generations the large claws trait prevails, while the small claws trait decreases because crabs with larger claws are more suitable. According to this, it is expected the percentage of crabs with large claws would increase.

Pumping carbon dioxide directly into the deepest zones of the ocean has been proposed as a strategy to mitigate climate change.
AnnyKZ [126]
Pro: Pumping carbon dioxide directly in to the deepest zones of the oceans can have a great deal in lessening the greenhouse gases that are produced within the Earth's atmosphere. 

Con: Some organisms are tolerant to such practice, but some experiments have yielded that some organisms are not and can die from such exposure to too much carbon dioxide mixing with other chemicals that are found underwater. 

Permanent Solution: Greenhouse gases can be minimized if there will be regulations regarding the production of goods in factories, mines, and agriculture. If these things are regulated, the release of such bad gases will be lessened and nothing underwater will be harmed.
