someone plz answer asap

Answer 1

+M EFFECT ORDER

–O^− > –NH2 > –NHR > –OR > –NHCOR > –OCOR > –Ph > –F > –Cl > –Br > –I

-M EFFECT ORDER

–NO^2 > –CN > --S(=O)2−OH > –CHO > –C=O > –COOCOR > –COOR > –COOH > –CONH^2 > –COO− 

and 

-M effect ∝ acidic strength 

+M effect ∝ basic strength

(i) -COOH

(iv) -CONH2

(ii) -OH

(iii) -NH2

so (i) > (iv) > (ii) > (iii) 

that's why (c) is correct answer
