I think it would be o-nitro-anniline (as in this case there is no mention of acetylation) there is no queation of blocking the ortho side by bulkier group.In addition to that in ortho position H-bonding confers additional stability.So I have done it as o-nitro anniline.Rest depends on WBJEEB

Para will be major product! Always remember that Only and only i case of Methyl attached to benzene will form ortho as major product on chlorination,nitration or Hbonding otherwise para will be always the major product formed!
I do agree with sir,s reason as "ice cold condition can never change the mechanism of a chemical reaction".However as a result of this,the rate of this reaction will become extremely slow and So "papa" will be the most easily formed & major product in this reaction.(NCERT TEXTBOOK-AMMINE chapter)
