Final answer:
The 'true locality' rule requires comparing a physician's actions to the standard of care in their exact locality. This rule is used in medical malpractice law but is considered outdated due to advancements in medical practice standardization.
Step-by-step explanation:
The statement that is true about the "true locality" rule (TLR) is option a. The TLR requires the court to look at the standard of care used in the exact locality of the physician. This rule is applied in medical malpractice law and takes into account the local standards of practice that may vary between different geographic areas. The concept behind this is to compare the physician's actions to those of a reasonably competent practitioner in the same area, considering the specific local practices and conditions. However, with the increasing availability of information and the standardization of medical practices, the TLR is considered outdated in many jurisdictions and has been replaced by a more national or regional standard.
