Hey,
Thanks for asking this question.
Correct answer is NF₃
Basicity order from least to most is,
NF₃ < NCl₃ < NBr₃ < NI₃
Main reason for this order is that-
More electronegative halides attract negative charge & hence reduce its availability.
Hope this answer helps.

Answer:
NF₃ is the least basic trihalide among due to the increased electronegativity of Fluorine. Positive charge next to highly electronegative atom is least stable.
Explanation:
Trihalides of nitrogen:
- Because nitrogen atoms have a lone pair of electrons/unshared pair of electrons, trihalides of nitrogen are Lewis bases.
- Nitrogen has the electrical configuration 1s² 2s² 2p³. As a result, it still has lone pair electrons of 2s when it produces trihalides. As a result, they serve as a Lewis base.
- Lewis bases must be able to give electrons to other Lewis bases.
- In the halogens, fluorine is the most electronegative element, followed by chlorine, bromine, and iodine.
- Fluorine's strong electronegative nature attracts electrons to itself, making it difficult for the nitrogen atom to transfer its lone pair of electrons. As a result, NF₃ is the least basic. This pattern follows the halides' electronegativity strength.
- Iodine is the most basic trihalide of nitrogen because it is the least electronegative.
