Please tell me if any of the following is true:

∂

_{μ}

^{†}= -∂

_{μ}

∂

_{i}

^{†}= -∂

_{i}

∂

^{μ}

^{†}= -∂

^{μ}

∂

^{i}

^{†}= -∂

^{i}

I'm studying QFT and I don't know how to proceed when I have to take the adjoint of a derivative. Sometimes it looks like one of these has to be true, sometimes it doesn't, and I don't know what to think anymore.

Thanks for your time
