Who among the following Mughal officers carried the dual responsibility of military and administration?

Mansabdar

The correct answer is Option (4) → Mansabdar

The Mughal administrative system had at its apex a military cum-bureaucratic apparatus (mansabdari) which was responsible for looking after the civil and military affairs of the state. Some mansabdars were paid in cash (naqdi), while the majority of them were paid through assignments of revenue (jagirs) in different regions of the empire. They were transferred periodically.
