Option: 2

In N\! H_{3} lone pair is present in pure s- orbital while in P\! H_{3} lone pair is present in one of the sp^{3}  hybridised orbital.


Option: 3

In N\! H_{3} lone pair is present in one of the sp^{3} d hybridised orbital while in P\! H_{3} lone pair is present in pure s- orbital

In N\! H_{3} lone pair is present in one of the sp^{3} hybridised orbital while in P\! H_{3} lone pair is present in pure s-orbital.

Hence, lone pair donation capacity of N\! H_{3} is stronger than P\! H_{3} .

Therefore, option number(1) is correct.
