How are people destroying wildlife?

- Gradually (ক): This option suggests that the destruction of wildlife is happening slowly over time. While this may be true in some cases, it does not convey the forcefulness or severity of the actions.

- Silently (খ): This option suggests that the destruction is occurring quietly or without much attention. While human activities may sometimes go unnoticed, this word choice does not necessarily capture the nature of the harm inflicted on wildlife.

- Harshly (গ): This option indicates that people are causing harm to wildlife in a severe, rough, or brutal manner. It implies forceful and damaging actions that have significant negative impacts on wildlife populations.

- Maliciously (ঘ): This option suggests that people are intentionally causing harm to wildlife with ill intent or wickedness. While human activities may indeed be harmful to wildlife, the term "maliciously" specifically implies a deliberate and malevolent motive.

Selection of "Harshly": Considering the severity and forcefulness of human activities that negatively affect wildlife populations, "harshly" is the most appropriate choice.
