Select the correct statements about the basicity of aromatic amines in water.

In aniline the lone pair is delocalised into the ring, making it weaker than $\mathrm{NH}{}_3$. A para methyl group donates electrons and raises basicity, while a para nitro group withdraws electrons and lowers it. A para chlorine lowers basicity because its -I effect outweighs its weak +R effect, so the last statement is false.
