On September 1st 1939, Germany invaded Poland. Britain and France had a defense agreement with Poland and demanded that German troops withdraw. Germany didn't respond to the demand so on September 3rd 1939, Britain and France declared war on Germany.
Actually, it was Hitler who declared war (again). England and America prepare for war because they thought it wouldn't end that easily.
Because Germany invaded Poland with whom Britain had a mutual defence pact.
Britain declared war on Germany because Germany attacked Belgium in order to strategically invade France. Britain vowed to protect Belgium, so Britain joined World War I.
Britain and France had offered a guarantee to Poland that if she was attacked by Germany they would come to her aid. When Germany subsequently invaded Poland, Britain and France gave Germany an ultimatum, demanding the withdrawal of German troops from Poland. Failure to do so would result in a state of war.
The specific reason was that German forces invaded Belgium on their way to France. Britain, France and Prussia (the key forerunner of Germany) had guaranteed Belgian neutrality in 1839 (and again in 1875). Moreover, Britain was an ally of France and was not willing to let a substantial part of the coast opposite Britain fall into unfriendly hands.
Britain and France declared war on Germany on September 3, 1939. The reason was because Germany had launched a military invasion of Poland two days earlier, even though Britain and France had told Germany not to do so.

No. What possible reason would Britain have had for that?
You don't mention the options you were given, but the formal reason was that Britain was bound by the Treaty of London of 1839, in which it undertook to 'defend' Belgium if it were ever attacked. The British explicitely mentioned this Treaty in their war declaration against Germany.
Great Britain declared war on Germany in response to there invasion of Belgium.
Belgium was the cause of friction between Great Britain and Germany in WW1. Belgium and Great Britain were allied, so when Germany invaded Belgium, Great Britain was obligated to side with Belgium and declare war.
