Based on the given passage, answer the question:
What will be the result of exercising caution while using a mobile phone?

The text states: "वैसे मोबाइल फोन के प्रयोग से हमें लाभ ही अधिक हैं। बस, हमें इसके प्रयोग में कुछ सावधानियाँ अवश्य बरतनी चाहिए।" (By the way, we gain more benefits from the use of mobile phones. We just must exercise some caution in its use). Exercising caution ensures we secure its benefits (लाभ) rather than the troubles. Thus, option A is the intended logical answer.
