Best Answer Explained in Below-:

The statement "The people in Asia mainly eat rice" can be rephrased to retain the meaning while using a different syntax. The key components of the original sentence are the subject (people in Asia), the action (eat), and the object (rice). The goal is to ensure that the rephrased version accurately conveys that rice is a predominant food staple for the people residing in Asia.

Option A, "Rice is mainly eaten in Asia," effectively accomplishes this. It maintains the focus on rice as the central element while stating that its consumption is prevalent in Asia. The structure also employs the passive voice, subtly shifting the focus to rice rather than the people eating it, which aligns with the essence of the original statement.

Conversely, option B ("Rice is mainly eaten by Asia") inaccurately suggests that Asia, as a place or entity, consumes rice, which is not the intended meaning. Option C ("Rice is mainly eating in Asia") is grammatically incorrect, as it improperly uses "eating" instead of "eaten," creating confusion about the action. Lastly, option D ("Asia is mainly eaten by rice") is nonsensical, as it implies that rice consumes Asia, which is contrary to the logic of food consumption.

Thus, option A is the only choice that accurately reflects the original statement’s meaning.
