As we have learnt,

Members of Carbon family form covalent hydrides of type \mathrm{EH_4}. Its formation tendency decreases down the group due to lessening of the \mathrm{E-H} bond energy.

Order of tendency of formation of hydride is

\mathrm{C > Si > Ge > Sn >Pb} 

Therefore, option (1) is correct.
