A) ch1 = 'A', ch2 = ' ', alpha = 18
B) ch1 = 'A', ch2 = '1', alpha = 8
C) ch1 = 'A', ch2 = ' ', alpha = 1
D) ch1 = 'A', ch2 = '
', alpha = 1

The statement does not contain any input or output operations, so the values of ch1, ch2, and alpha must have been initialized or assigned earlier. Based on the input "A 18", we can determine that ch1 is assigned the value 'A' and alpha is assigned the value 18. The space between 'A' and '18' is not read into ch2, so its value remains ' '. Therefore, after the statement executes, ch1 = 'A', ch2 = ' ', and alpha = 18.
