Rats are nocturnal animals and tend to sleep during the day.

Certainly! Let's break down the sentence and explain the meaning:

Original Sentence:

"Rats are nocturnal animals and tend to sleep during the day."

Explanation:

- Nocturnal Animals: Rats are mentioned as "nocturnal animals," indicating that they are primarily active during the night.

- Tend to Sleep During the Day: This part suggests the behavioral tendency of rats to sleep during the daytime.

Meaning:

The sentence conveys that rats are creatures active during the night, and as a consequence of being nocturnal, they have a tendency to sleep during the day.

Analysis of Options:

- ক. "are certain": This does not convey the idea of a behavioral tendency related to sleep; it is not a suitable alternative.

- খ. "are prone": This option is the closest in meaning. "Prone" implies having a natural tendency or inclination towards a particular behavior or condition, fitting the context of rats sleeping during the day.

- গ. "are afraid": This does not capture the meaning of the original sentence. It introduces a different concept related to fear.

- ঘ. "are induced": This does not fit the context of the original sentence. "Induced" implies being influenced to take a certain action, which is not the intended meaning here.

In summary, option খ ("are prone") is the closest in meaning to the original sentence, conveying the natural tendency of rats to sleep during the day due to their nocturnal nature.
