The correct answer is - mudslides.
The hurricanes bring in a very large amount of water with them in a very short period of time. Because of this, the soil gets over-saturated with water, and this causes the surface layer of the soil to start moving. The mudslides usually appear at steep places, and they are combination of large amounts of water and soil that have mixed and created fast moving mud river. The mudslides, because of there speed and sudden appearance, are extremely dangerous, and they cause very big damage, both in human lives and material damage.

Explanation:
A scientific method is the best procedural approach to explain the natural phenomenon. The method includes various steps which begin with the making the observation. The observation leads to the asking the scientific questions which could be answered by proposing a hypothesis.
The hypothesis must be tested through experiments which could prove and disprove the hypothesis and can answer the natural phenomenon.
<u>Case-I</u>
In the given situation of the question in which a person notices or observes the fields of grass and grass and native flower. Since the researcher notices the fields, they are performing the first step of the method that is "making an observation" and thus Option-B is the correct answer.
<u>Case-II</u>
In the situation, which discusses the number of birds in the fields shows the "dependent variables". The dependent variable is the parameter which is studied in the experiments. Since in the given conditions the number of birds is being studied, therefore, Option-B is the correct answer.
