Magnitude of induced emf produced in a coil when a magnet is inserted into it depends on the

Question

$\begin {array} {1 1} (1)\;\text{No. of turns in the coil} & \quad (2)\;\text{Resistance of the coil} \\ (3)\;\text{Magnetic moment of the magnet} & \quad (4)\;\text{Speed of approach of the magnet} \end {array}$

 

$\begin {array} {1 1} (a)\;1,2 & \quad (b)\;2 \\ (c)\;3,4 & \quad (d)\;1,3,4 \end {array}$
