Which of the following group (s) is/are `o-` and p-directing ?

Which of the following groups are ortho-end para-directing :

Which of the following group (s) is/are m-directing ?

Which of the following groups are m- directing :

Which of the following groups are meta-directing :

Directing nature of substuted aromatic compound is decided by stability of sigma -complex is stablise at o- and p- position by attack of electrophile then group is o- and p- directing but if sigma -complex is stabilise at m- position then gruop will be meta directing. On the basis of above explanation find out correct answer of following questions. Which of the following is not o- and p- directing ?
