Refined grain products like bread, flour tortillas, white rice, cornmeal, crackers etc are enriched with riboflavin, niacin, iron and thiamin.
Enriched grains is finely ground endosperm of the kernel. Enriched grain products are good as a source of iron and four types of vitamin B which includes niacin, thiamin, folic acid and riboflavin and also contains some complex carbohydrates.
Wheat and rice are a staple diet in many regions of the world but excessive polishing and refining the cereals removes the essential nutrients or vitamins which have their own important physiological roles.
Potential K- strategists include humans.
K- strategist:
The term "K-selected" or "K-strategist" refers to species whose populations vary at or close to the carrying capacity (K) of the ecosystem in which they live. Compared to r-selected species, K-strategist species have remarkably constant populations and generate relatively few offspring, but those offspring typically grow to be rather big. Lengthy gestation durations of many weeks, slow development (and hence prolonged maternal attention), and long longer lifespans are traits of K-selected species. Additionally, they typically live in ecological groups that are generally stable, including premature or climax forests.
R-strategist:
They are creatures that have high reproduction rates followed by high death rates, resulting in populations with wildly variable numbers, according to the concept of r-selected species (or r-strategist). This term is based on the concept of "r," a variable in the ecology of animal populations that denotes a species' maximal reproductive potential. The populations of r-selected species will be small outside of the mating season. R-selected organisms begin to generate a lot of progeny as soon as reproduction begins.
Therefore it is concluded that the final choice is option C, i.e., humans.

Considering the question is asking only for the percentage of the P allele, then the correct answer is A - 89 percent.
This is correct because we always have a combination of 2 alleles, either PP, Pp or pp. If from all these the p allele is found only in 11% then the remaining 89% are from the P allele.
