Japatan
Formação
- V ば形 + こそ(例: 思えばこそ)
- Vている → Vていればこそ
- いA(〜ければ) + こそ
- なA / N + であればこそ
Explicação
Like 〜からこそ, it singles out a reason and stresses "it is precisely for this reason." The sentence often ends in 〜のだ and expresses the speaker's claim or evaluation. It is often used to explain the true, positive reason behind something that looks negative. It is a formal, written expression.
Exemplos

It is precisely because they care about their children that parents speak to them strictly.

健康であればこそ、好きな仕事にも打ち込めるのである。
It is precisely because you are healthy that you can devote yourself to the work you love.
Observações
The form is ば form + こそ, never するばこそ. It is usually not used for simple causes or bad results; it emphasizes a reason the speaker sees as meaningful.

Resposta e explicação
Resposta: 4 相手を尊敬していればこそ、言いにくいことも正直に伝えるのだ。
Sentence 4 means "It is precisely because I respect them that I tell them even hard things honestly." 1 and 3 state a simple cause or bad result, and 2 is an invitation, so they are wrong.
