You have a halachic question. Unknown to you, there is a dispute on the matter. Some rule as (A) and some rule as (B). You ask your Rav. He will give you one of three answers:
(1) The answer is (A).
(2) There is a dispute on the matter. Some rule as (A) and some rule as (B). But I rule as (A) and that's what you must do since you are a member of my community.
(3) There is a dispute on the matter. Some rule as (A) and some rule as (B). So you can do either one.
Which is the best rabbinical answer? Or are they halachically equivalent?
