The correct answer is Option D.
Because C4H9NH2 is primary amine and can form hydrogen bonding more than secondary amine (C2H5)2NH and tertiary amine C2H5N(CH3)2 . More hydrogen bonding leads to strong bonding between the molecules, hence increases the boiling point.

Boiling Point Comparison of Amines:
1. n-C4H9NH2 has the highest boiling point among the given options.
2. The boiling point of amines depends on the strength of intermolecular forces, which are governed by molecular weight and hydrogen bonding.
3. As the molecular weight of a compound increases, its boiling point also tends to increase due to stronger van der Waals forces.
4. In the given options, n-C4H9NH2 has the highest molecular weight compared to the others.
5. Additionally, n-C4H9NH2 can form strong hydrogen bonds between the NH2 groups, further increasing its boiling point.
6. The other options have lower molecular weights and may not have as many hydrogen bonding sites, leading to lower boiling points.
7. Therefore, n-C4H9NH2 (option D) has the highest boiling point due to its higher molecular weight and potential for hydrogen bonding.
