As we have learned

Positively charged electrophiles -

Chemical species having capacity to attack e- rich portion of substance.

- wherein

H^{+},Cl^{+},Br^{+},NO^{+},NO_{2}^{+},R^{+}, 

 

 In aromatic nitration, the reagent NaNO_2 / HCl  gives NO_2^+ electrophile (positively charged electrophile) which reacts with substrate to give nitro product 

Therefore, option (4) is correct.
