The project to develop a proprietary custom support system for a major mortgage company is underway. This is the largest project E-TEK has ever undertaken and E-TEK is concerned about possible liability due to failure to meet the schedule or to perform the work in accordance with the agreement. E-TEK responds to these concerns by obtaining Professional Liability Insurance. Of the following, what best describes the type of risk response represented by this response?

a. Risk mitigation, which mitigates negative risk by taking actions to lessen its impact

b. Risk avoidance, which avoids negative risk by taking actions to prevent it

c. Risk acceptance, which accepts negative risk and has a plan to deal with it if it occurs

d. Risk transference, which avoids negative risk by transferring or reassigning responsibilities
