What is the official motto of the Border Security Force BSF of India?

Introduction / Context:
The Border Security Force, commonly abbreviated as BSF, is one of the central armed police forces of India. It is responsible for guarding the land borders during peace time and preventing trans border crimes. Like many defence and paramilitary organisations, BSF has a short formal motto that reflects courage, sacrifice and commitment. General knowledge exams frequently ask for the exact wording of such mottos, so candidates need to memorise them accurately rather than relying on approximate phrases.

Given Data / Assumptions:

• The organisation mentioned is the Border Security Force of India.
• The question asks specifically for its motto, not its role or formation year.
• The options are four short phrases that all sound like they could belong to a defence organisation.
• We assume the motto is the formally adopted phrase used on emblems, flags and official documents.

Concept / Approach:
The correct approach is simple factual recall. BSF uses the motto Duty unto Death, which expresses the idea that personnel are bound to carry out duty even at the cost of their lives. Other phrases such as Service Before Self are associated more closely with the Indian Army, and generic sounding lines like Protection and Security or Service and Loyalty are not the official motto of BSF. Therefore, recognising which phrase is historically linked to BSF is crucial for answering correctly.

Step-by-Step Solution:
Step 1: Identify the organisation clearly as the Border Security Force, a central armed police force responsible for guarding land borders.Step 2: Recall from standard general knowledge sources that BSF adopted the motto Duty unto Death.Step 3: Compare this exact wording with the options and observe that one option matches it perfectly.Step 4: Reject the remaining options because they either belong to other forces or are generic motivational slogans rather than the official BSF motto.

Verification / Alternative check:
Official BSF publications, recruitment brochures and its emblem show the motto Duty unto Death prominently along with the crest. Government websites and authentic defence related reference books repeat the same phrase when describing BSF. If a candidate visits a reliable source or looks at images of the BSF flag and badge, this motto appears consistently. Such cross verification offers strong confirmation that Duty unto Death is the only correct answer.

Why Other Options Are Wrong:
Service Before Self is a famous motto associated with the Indian Army and can therefore mislead candidates, but it is not the motto of BSF. Protection and Security is a broad phrase that describes what many forces do but it is not adopted formally as the BSF motto. Service and Loyalty again sounds appropriate but does not appear in official BSF insignia or documents. Because the question asks for the exact motto, any phrase that does not match the officially used wording must be treated as incorrect.

Common Pitfalls:
A common mistake is to memorise defence mottos in a confused way, mixing up the one for BSF with those for the Army, Navy or Air Force. Another pitfall is to choose the option that sounds nicest in English rather than recalling which phrase is actually printed on the emblem. To avoid these errors, students should create a small list pairing each force with its motto, for example BSF equals Duty unto Death, Army equals Service Before Self, and revise this list regularly before exams.

Final Answer:
The official motto of the Border Security Force of India is Duty unto Death, so the correct option is Duty unto Death.
