Historically, Women Were Considered the Obvious Choice for Nursing Sick

Historically, women were considered the obvious choice for nursing sick patients, because:

A) caring for others was an extension of their homemaker role.
B) early nurses were nuns, so the public was used to women in nursing.
C) men, who had education, were reluctant to try nursing.
D) women were often at home anyway, so caregiving was easy.
