Needles $N_1,N_2$ and $N_3$ are made of a ferromagnetic, a paramagnetic and a diamagnetic substance respectively. A magnet when brought close to them will:

1. A
   attract all three of them
2. B
   attract $N_1$ and $N_2$ strongly but repel $N_3$
3. C
   attract $N_1$ strongly, $N_2$ weakly and repel $N_3$ weakly
4. D
   attract $N_1$ strongly, but repel $N_2$ and $N_3$ weakly
