Last week's answer: (a) Runner is out; 3B's actions were unintentional..

If a fielder purposely tries to block a runner’s vision on a tag play, an umpire can rule that he is guilty of obstruction. Once the defensive team attempts to make a play on the runner being obstructed, he is awarded the base toward which is running. If, however, the umpire deems the action unintentional, then obstruction is not called and the play proceeds with intervention.

Last week's answer: (c) Run scores if A touches home before B is putout.

According to ASA rules, the putout of a runner for failure to tag up is a time play (not a force play). When a time play occurs, all runs scored before the out was recorded are permitted to stand. When a force play occurs (e.g., a 6-4-3 double play with men on 1 and 3), no runs are permitted to score, regardless of when the lead runner crosses the plate.

Last week's answer: (b) Action continues and the result of the play stands

A batter is only out when struck by a batted ball if: (1) the infraction occurs before all relevant fielders have had a chance to make a play on the ball; or (2) if the umpire deems that the runner intentionally made contact with the batted ball  In this example, the ball had passed the drawn-in infield, meaning that no fielders had a chance at field the ball. As a result, the ball is live and the results of the play stand.

 Last week's answer: (a) Batter goes to 2B; runner from 2B scores When an overthrow is made, all runners, including the batter, are awarded TWO bases from the RELEASE of the throw. No distinction is made based on whether the throw is from the outfield or the infield. The reason a throw from an infielder seemingly results in one base is because in most cases the batter has not yet reached first base before the throw is made. As a result, the two bases awarded are actually 1B and 2B.

Last week's answer: (e) The offense is allowed to pick choice 2 or 3.

When a batter makes contact with the catcher's glove BEFORE completing his swing, catcher's interference is called. Catcher's interference results in a delayed dead ball, which allows the offense to either keep the result of the play or opt to have the batter awarded first base. If the latter is chosen, a error is charged to the catcher and no runners are allowed to advance unless forced by the batter being awarded first base.
