What is the correct transformation for: "He .................................. for dinner at the weekend"?

The sentence "He .................................. for dinner at the weekend" suggests that someone is extending an invitation or proposal regarding having dinner together. The correct answer emphasizes not only the act of inviting but also implies a level of formality or suggestion regarding the dinner arrangement.

The phrase "suggested that she come over" effectively conveys that he is proposing the idea of her joining him for dinner, and it captures the nuanced nature of that invitation. The use of the word "suggested" indicates that he is recommending or bringing up the idea, which is appropriate for the context of a dinner invitation.

While other options might imply an invitation, they lack the same subtlety or formality. For instance, while "invited her over" is straightforward, it lacks the suggestive aspect present in option B. The same applies to "asked her to come" and "proposed having her over," which either come off as more direct invitations without the nuance of suggestion or imply a different focus. Thus, option B stands out for its appropriateness in conveying both an invitation and a polite suggestion for the occasion.
