Answer: D. Daniel, who has worked his way up from entry-level to manager of Cecily's team within the last five years.
Explanation:
Daniel would be in the best position to help her out of all her colleagues because he started from where she started and has now grown to a higher level. He has also been at the company for a long time and knows how things work.
His advice and mentorship woth good intent, will provide Cecily with valuable help in moving forward because she would have a person who has already trodden the path for her and knows what to do and what not to do.
The other options have either not stayed in the job long enough or have stayed in the job for too long to be the best mentors.
