Why? Give explanation.

I think glassy aggregates will not form bonds easily with other components of concrete mixture.

Why only glassy rather than smooth? Smooth texture also not make good bond and fais in shear and compresive stress.

Glassy and smooth are different. A smooth aggregate for convenience can be a rounded aggregate also. It will have microscopic pores even though it may appear smooth to us. The bonding between the cement and aggregate would happen at this level rather than on the macro scale. Now, in the case of glassy, the surface lacks this microscopic rough surface. Hence Glassy is the correct answer.

How it can not be honey comb and porous?

Agree @Midhun Madhav.
The surface lacks this microscopic rough surface, that's why it is very suitable for concrete mix.
D) honey combed and porous will be the answer.
