• A. They undergo little thermal expansion.​
• B. They have low density.
• C. They have strong intermolecular forces.
• D. They have low diffusibility.

Answer 1

The correct option is B They have low density.

Properties of Solid​:

1. Have definite mass, ​volume and shape.​
2. Constituent particles ​have fixed positions​.
3. Intermolecular distances are short ​between constituent particles​.
4. Intermolecular forces are strong.
5. They are incompressible ​and rigid.​
6. They have high density.
7. They undergo little thermal expansion.​
8. They have low diffusibility.

Only option (b) is incorrect.
