The total number of railway zones that exist is
A
Correct answer
Explanation
Indian Railways had 17 zones for several years after being reorganized from 16 zones in 2002 with the addition of several new zones. The number has since increased to 18 zones with the addition of more zones. Options 9 and 16 are outdated, while 'none of these' could be argued depending on when this question was framed.
