To answer this question, let's go through each statement:
i. An incident may be closed without being fixed. - This statement is true. In incident management, it is possible for an incident to be closed without being fixed if it is determined that the incident is not valid, a duplicate, or cannot be reproduced.
ii. Incidents may not be raised against documentation. - This statement is false. Incidents can be raised against documentation if there are errors, omissions, or inconsistencies in the documentation that impact the users.
iii. The final stage of incident tracking is fixing. - This statement is false. The final stage of incident tracking is not necessarily fixing. After an incident is reported, it goes through various stages such as triage, investigation, resolution, and closure. Fixing is just one of the stages in the process.
iv. The incident record does not include information on test environments. - This statement is false. The incident record may include information on test environments if it is relevant to the incident, such as if the incident occurred during testing or if it is specific to a particular test environment.
Based on the above analysis, we can conclude that statement i is true, and statements ii, iii, and iv are false.
Therefore, the correct answer is B.
