If \(S\) is the sum of the digits of a given number, \(T\) is the sum of the digit of \(S\), and \(G\) is the sum of digits in \(T\). For example \(S\) of 987 is \(9+8+7 = 24\), \(T\) of \(S\) is \(2+4 = 6\) and \(G\) of 6 is 6. Therefore \(G\) of 987 is 6. Which of the following has the greatest \(G\)?

If \(S\) is the sum of the digits of a given number, \(T\) is the sum of the digit of \(S\), and \(G\) is the sum of digits in \(T\). For example \(S\) of 987 is \(9+8+7 = 24\), \(T\) of \(S\) is \(2+4 = 6\) and \(G\) of 6 is 6. Therefore \(G\) of 987 is 6. Which of the following has the greatest \(G\)?

A. 94123 B. 91964 C. 64678 D. 62355 E. 45689

The explanation follows as under: \(G\) of 45689 is 5 whereas the rest have \(G\) smaller than 5.

A. \(S = 9+4+1+2+3 = 19\), \(T = 1+9 = 10\) and \(G = 1+0 = 1\).
