Test Time

[bbsbvb83]

I just found a play in the case book that makes me think "B" must be the correct answer.

8.4.2 SITUATION V: R1 is advancing toward second base on a ground ball by B2 and is obstructed by F4. R1, in an attempt to avoid F4, dives over the top of F4.
RULING: R1 is declared out immediately, and unless he makes contact or alters the play of F4, the ball remains live. The act of obstruction is superseded by the act of diving over a fielder.

If diving over a fielder were considered interference, I believe we would have an immediate dead ball. I suppose I just answered my own question, although it seems like the rules book is a bit misleading here.
