During Her Research in the Community of Gerai in West

During her research in the community of Gerai in West Borneo, anthropologist Christine Helliwell described how her gender was uncertain among the Dayak for the duration of her fieldwork. This was because

A) they didn´t know she had breasts and a vagina due to the sarong she wore.
B) for the Dayak, a "woman" has children and at that time Helliwell didn´t have any.
C) for the Dayak, a "woman" is a person who excels at distinguishing types of rice and its preparation, but Helliwell did not master these tasks.
D) none of the above.
