Read the following context and choose the best option to answer the question.
Context: It turned out to be Channing who gave me a quick rub before more kids bugged him to sign their stuff . Not fair , I clearly need a massage more than they need autographs . Other than my pleasant , albeit brief , massage time today , it was remarkably boring . I did more deliveries , saw the old man in his stall , walked to the Bread Basket for soup , sat in the booth since there was nothing to do and had to shoot the paddock for the feature and then get back to the office to switch cameras and then do the turn .
Question: Why did Channing signed stuff for kids ?
Options: 
A. Because he wanted to use up kids ' pens .
B. Because his hands were tired .
C. Because kids would bite him if he did n't .
D. None of the above choices .
