The correct statement about the given chemical reaction is :

1. -NH₂ group is ortho and para directive, so product (B) is not possible.

2. Reaction is possible and compound (B) will be the major product.

3. The reaction will form sulphonated product instead of nitration.

4. Reaction is possible and compound (A) will be major product. 

In the following reaction, the reason why meta-nitro product also formed is:

1. Low temperature

2. –NH₂ group is highly meta-directive

3. Formation of anilinium ion

4. –NO₂ substitution always takes place at meta-position
