Answer:
The correct answer is option A, Gastrula
Explanation:
Gastrula has three layers of cell and it is the phase in which single layered blastula matures and get converted into multilayered structure.
However, Morula is formed after the formation of blastula through the process of blastulation. In the Morula phase, blastomers get arranged in a spherical shape after the zygote split. And zygote is formed at a very early stage of fertilization .
Thus , gastrula is the correct answer as it is the stage which comes after zygote and morula and thus get developed into more compact mass of cells.

Colostrum is the earliest breast-milk produced, beginning in mid-pregnancy (12-18 weeks) and is continually produced for the first few days after baby's birth, it provides all the nutrients and fluid that your newborn needs in the early days, as well as many substances to protect your baby against infections. Mothers with untreated and active tuberculosis infections are not advised to breastfeed. They may breastfeed after their infection is cured or brought under control so that it does not spread to the infant.
