If R2 scores after an overthrow on an obstructed play, what option does the coach have?

When a runner scores as a result of an overthrow on an obstructed play, the coach has the option to choose between accepting the penalty for obstruction or the result of the play itself. This means that if the obstruction led to the overthrow, which allowed the runner to score, the coach can opt to accept the obstruction call. By doing this, the runner could potentially be allowed to score, and the score would stand based on the obstruction rules. In this context, the coach's decision can influence whether they want to take the penalty or benefit from the outcome of the play. Thus, the correct response is that the coach has the option to accept either the obstruction penalty or the result of the play.
