Which of the following is Wurtz-Fittig reaction?

${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{I}+2\mathrm{Na}+{\mathrm{ICH}}_3\to {\mathrm{C}}_6{\mathrm{H}}_5-{\mathrm{CH}}_3+2\mathrm{NaI}$

Both 2 and 3

${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{I}+\mathrm{Cu}+{\mathrm{IC}}_6{\mathrm{H}}_5\to {\mathrm{C}}_6{\mathrm{H}}_5-{\mathrm{C}}_6{\mathrm{H}}_5+{\mathrm{CuI}}_2$

${\mathrm{CH}}_3\mathrm{I}+2\mathrm{Na}+{\mathrm{ICH}}_3\to {\mathrm{CH}}_3-{\mathrm{CH}}_3+2\mathrm{NaI}$
