What is the oxidation state of chlorine in iron(iii) hypochlorite?

The sum of the oxidation states of the individual atoms should be equal to the the net charge of the compound /ion. 
Molecular formula of iron(III) hypochlorite is Fe(ClO)₃
This is made of a cation and anion. Cation is Fe³⁺ and anion is hypochlorite ion - ClO⁻
the net charge of the ion is -1
oxidation state of Cl - x and oxidation state of O - -2
x + (-2) = -1
x - 2 = -1 
x = -1 + 2 
x = +1
Therefore oxidation state of Cl is +1

What are the choices?

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.
