Statement A : Typical angiosperm embryo develops near to the micropylar end of the embryo sac.
Statement B : Coleorrhiza encloses radical and the root cap.
 

The egg is located at the micropylar side of the embryosac and hence syngamy occurs at the micropylar end of the embryo sac and it is there that the embryo also develops. 
The embryonal axis has the radical and root cap enclosed in an undifferentiated sheath called coleorrhiza.
