The normal time for the job is 15 minutes. 
Adding the allowances: 
- 10% for personal needs = 1.5 minutes 
- 5% for unavoidable work delays = 0.75 minutes 
- 3% for work fatigue = 0.45 minutes 
Total allowance time = 2.7 minutes  
Therefore, the standard time for the job is: 
15 minutes + 2.7 minutes = 17.7 minutes
Rounding up to the nearest minute gives us C) 18 minutes.
