Identify the suitable reagents for the conversion of benzene to fluorobenzene.

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A)$ : Chlorine is an electron withdrawing group but it is ortho,para directing in electrophilic aromatic substitution.
Reason $(R)$ : Inductive effect of chlorine destabilises the intermediate carbocation formed during the electrophilic substitution,however due to the more pronounced resonance effect,the halogen stabilises the carbocation at ortho and para positions.
In the light of the above statements,choose the most appropriate answer from the options given below :
