Question

in which sentence is the adverb clause punctuated correctly? when i went to the game i caught a foul ball. when i went to the game, i caught a foul ball. i caught a foul ball, when i went to the game.

Explanation:

An introductory adverb clause (like "When I went to the game") that comes before the main independent clause needs to be followed by a comma to separate the dependent clause from the independent clause. If the adverb clause comes after the main clause, no comma is needed. The first option omits the required comma after the introductory clause, and the third option incorrectly uses a comma before a trailing adverb clause.

Answer:

B. When I went to the game, I caught a foul ball.
