The answer is A . You can infer(predict) an event based on evidence or foreshadowing
Oh I’ve read this book last year. So what can I remember about Jonas’ father from these details that the author shares with us is that now that Jonas’ father found a child named Gabriel, they have to give care with this child since their family signed this agreement.
Since nothing is underlined, I am going to make an educated guess that the underlines clause is "who had worked with the business person". If that is the case, the correct answer would be D - adjective clause. It is a relative clause, to be more precise, because it starts with a relative pronoun "who", but that is a part of adjectival clauses, so that is the correct answer.
