To find the probability of a student attending a religious school in a rural location, we need to look at the column for rural and the row for religious, which has a value of 5. 
The total number of students attending religious schools is 30 (5 + 25), and the total number of students in rural locations is 180 (40 + 140). 
Therefore, the probability is 5/30 or 1/6, which simplifies to approximately 0.167 or 16.7%. 
Therefore, the best choice is C.
