B, Field study. This is because she wants to find a number in a certain location that cannot be replicated. She needs to observe the amount of species so an Experiment does not work. A survey is a questionnaire and wouldn't help because she needs to see it herself. A lab study wouldn't replicate the rocky shores she needs to investigate.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
