It suggests that the speaker is recommending to check if the person has a permit or not, implying that there is a doubt or uncertainty about the situation. "If" and "when" do not convey the same meaning in this sentence.

    • Whether

    Correct Answer
    A. When
    Explanation
    The correct answer is "when." This is because the sentence is suggesting that the person should come in the summer because the weather is better during that time. "When" is used to refer to a specific time or period, which fits the context of the sentence. "If" and "whether" are not suitable in this case as they do not convey the idea of a specific time.
