Match the complex ions given in Column – I with the hybridization and number of unpaired electrons given in Column – II and assign the correct code: 
Column – I

	Column – I (Complex ion)		Column – II (Hybridization , number of unpaired electrons)
a)	${\left[\mathrm{Cr}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{3+}$	p)	dsp2,1
b)	${\left[\mathrm{Co}(\mathrm{CN}{)}_4\right]}^{2-}$	q)	sp3d2,5
c)	${\left[\mathrm{Ni}{\left({\mathrm{NH}}_3\right)}_6\right]}^{2+}$	r)	d2sp3,3
d)	${\left[{\mathrm{MnF}}_6\right]}^{4-}$	s)	sp3,4
		t)	sp3d2,2

	(a)	(b)	(C)	(D)
1)	r	p	t	q
2)	s	r	q	p
3)	r	q	s	p
4)	s	p	q	r
