As per the rules of bionomial nomenclature, the species name that is written correctly is C. Pelecinus polytyrator (or B, because you wrote two answers which are completely the same). You capitalize the genus name, but write the specific epithet in small letters.
Binomial nomenclature can be defined as a formal system of naming the species of the living things.

A diet deficient in calcium can cause osteopenia. The deficiency of calcium may Cause a low bone density which is a condition caused in osteoporosis. Hence the correct answer is B osteopenia.
If Bb gene is crossed with Bb, the offspring is produced with normal hearing because both the genes are recessive in which the deafness gene hide and the hearing gene is dominant so the offspring can hear sounds clearly. The dominant A gene is responsible for deafness and we can see the offspring BbxBb in which no dominant gene is present. The other three offspring are deaf because of the presence of dominant A gene in their genetic makeup.
