Answer:

Gastrulation.

Explanation:

Answer:

The correct answer is option d.

An illustration of epigenetic change is a microbe, which can stimulate modifications in the host DNA, causing suppression of defenses or weakening of individual cells. Epigenetic changes modify the physical composition of DNA.  

One of the examples of epigenetic change is DNA methylation. DNA methylation refers to the supplementation of methyl group, which inhibits some of the genes from getting expressed. One of the conditions of DNA methylation is cancer.  

In the majority of cancer, the tumor cells go through global hypomethylation. The tumor suppressed genes seem to turn highly methylated in the conditions of cancer.
