The correct choice features a very common error of pronoun case, which leads the sentence to incorrectly conclude with a preposition. Rather than using the subjective-case "who" in saying "who I am speaking to," it is correct to use the objective-case "whom." Sentences should never, in academic writing, end with a preposition.

It is very important to look both ways when one crosses the street because you never know when a car might come.
It is very important to look both ways when one crosses the street because you never know when a car might come.
The correct answer features inconsistent pronoun usage. Since the sentence first uses the pronoun "one," the sentence must remain consistent in its usage of that pronoun. It is incorrect to follow "one" (when used as a pronoun) with "you." The correct version of the sentence reads, "It is very important to look both ways when one crosses the street because one never knows when a car might come." This question interrogates the principle of consistent pronoun usage. None of the other options included any grammatical errors.
