The passage states that through ambiguity, 'a relationship of trust that transcends language is nurtured.' This directly supports the correct answer that it 'can become an opportunity to build a relationship of trust that goes beyond words.' Option A is wrong as ambiguity is not efficient. Option B is explicitly contradicted when the text says it 'carries the risk of creating misunderstandings.' Option C is also wrong, as the passage mentions 'entrusting it to the other person's interpretation,' which is a burden.
