Final answer:

Step-by-step explanation:
In the study of 90 cases of serial murder conducted by Yorker et al., it was found that 86 percent of the cases involved nursing personnel. When attempting to ascertain the percentage of these cases involving women, it becomes necessary to closely evaluate the phrasing of the question.
Since the question provides options as (a) 82, (b) Less than 30, (c) 55, (d) 49, and the provided information does not directly offer a percentage for this specific question, the correct response is left unidentified. Without additional context or source data from the study mentioned, delivering an accurate answer isn't possible.
However, the prompt provides an opportunity to discuss societal patterns and norms concerning intimate relationships, gender roles, and nursing as a predominantly female profession, highlighting trends such as the prevalence of female nurses in healthcare and the impact of gender-based violence.
