The correct translation of “ہمارے بہادر فوجی دل و جان سے مادر وطن کی حفاظت کر رہے ہیں” is "Our brave soldiers are defending our motherland with all their heart and soul." This translation accurately captures the nuance and intensity of the original Urdu phrase. The term "دل و جان سے" directly translates to "with heart and soul," signifying complete dedication, passion, and commitment. "مادر وطن" means "motherland," and "حفاظت کر رہے ہیں" translates to "are defending."
Other options, while close, miss the precise idiomatic expression. "With passion" (Option A) is less emphatic than "with all their heart and soul." "With all their zeal and zest" (Option C) is a plausible alternative but doesn't directly reflect "دل و جان." Option D changes "motherland" to "beloved land," which, while similar, isn't the most direct translation of "مادر وطن." The chosen answer perfectly conveys the profound devotion and sacrifice implied in the original Urdu sentence.
