• B. All of the above
• C. From N to As the melting point increases and from As to Bi it decreases
• D. As we go down the group metallic character increases

Answer 1

The correct option is B All of the above

Physical properties of group 15 elements:
1. On moving down the group, metallic character increases.
2. The correct order of boiling point is $N<P<As<Bi<Sb$
3. From N to As the melting point increases and from As to Bi it decreases.
Hence option (d) is the correct answer.
