Two Identical Pith Balls Supported by Insulating Threads Hang Side

Two identical pith balls supported by insulating threads hang side by side and close together, as shown below. One is positively charged; the other is neutral. We can conclude that

A) all field lines leaving the positively charged pith ball end on the neutral pith ball.
B) some of the field lines leaving the positively charged pith ball end on the neutral pith ball.
C) none of the field lines leaving the positively charged pith ball end on the neutral pith ball.
D) positive charge is transferred along the field lines until both balls have equal charges.
E) positive charge is transferred along the field lines until both balls hang along vertical lines.
