C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -When viewed in profile, female skulls have a rounded forehead (frontal bone). Male frontal bones are less rounded and slope backwards at a gentler angle. This ridge along the brow is prominent in males and much smoother in females.

Detailed explanation-2: -It is made up of much lighter bones than males, with smooth surfaces. The frontal and parietal eminences are larger than that of males. The orbits of a female skull are rounded and larger. In addition, females show more rounded and more upright foreheads.

Detailed explanation-3: -Pelvis is the most reliable skeletal element for sex determination. Skeletal differences mainly related to birth mechanism. Female pelves show a relatively larger birth canal.

Detailed explanation-4: -Which skull is most likely male? Male skulls tend to be larger and have larger or rougher appearances. Keep in mind ways that you could tell the differences between a male and female skull.
