    E) None of these

    Correct Answer: C

    Explanation Option [c] is correct because this is the only option which has digits sum equal to 19. The sum of the digits of all the other options is equal to 10. Let us see: [a] \[514=5+1+4=10\] [b] \[505=5+0+5=10\] [c] \[199=1+9+9=19\] [d] \[352=3+5+2=10\] Rest of the options is incorrect because of the correctness of option [c].
