As we learned

 

Hydrolysis of benzene diazonium salts -

By warming with water or treating with dilute acids. 

- wherein

C_{6}H_{5}N_{2}Cl+H_{2}O\rightarrow C_{6}H_{5}OH+N_{2}+HCl

 

 

When diazonium salt is treated with  H_{3}PO_{2}  and H_{2} .Its diazonium group is replaced by -H resulting in the formation of hydrocarbon.

Therefore, option (3) is correct.
