Answer:

d. a hollow ball of cells in an embryo

Explanation:

Blastula is a stage during early embryo development which arrives between morula stage and gastrula stage. This stage is characterized by a hollow ball of cells which surround a cavity known as blastocoele. This layer of cells which surround the blastocoele is known as blastoderm and it is formed by the repeated cleavages of zygote (fertilized egg). This cavity inside blastoderm i.e.  blastocoel is filled with fluid. Soon after the blastula develops fully, it turns into a gastrula and the process is called as gastrulation.

A dominant allele is written with a capital letter whereas a recessive allele is referred with a small letter.
