I'm pretty sure it's black soil
You're answer is A because when you think about it these creatures lived before any of the other creatures on your list
In certain flowering plants, the flower contain more stamen than pistil to increase chances of pollination.
The stamen is the male reproductive part of a flower and the pistil is the female reproductive part of the flower.
More stamen means more pollen. By producing more stamen and therefore more pollen, the chances of pollen coming into contact with the pistil are much higher especially since pollination depends on either wind or insects.
However, not all flowering plants have this arrangement.

Yes, it is true that Mammalian target of rapamycin pathway mutations cause hemimegalencephaly and focal cortical dysplasia.
Focal malformations of cortical development, including focal cortical dysplasia (FCD) and hemimegalencephaly (HME), are important causes of intractable childhood epilepsy.
Using targeted and exome sequencing on DNA from resected brain samples and non-brain samples from 53 patients with FCD or HME, we identified pathogenic germline and mosaic mutations in multiple PI3K/AKT pathway genes in 9 patients, and a likely pathogenic variant in 1 additional patient.
Our data confirm the association of DEPDC5 with sporadic FCD but also implicate this gene for the first time in HME. Our findings suggest that modulation of the mammalian target of rapamycin pathway may hold promise for malformation-associated epilepsy.
