Correct option is A
• Given expression: “Military supplies including weapons, ammunition, combat vehicles and maintenance equipment” refers to the complete set of war-related materials used by armed forces, especially weapons and ammunition and related military equipment.
• Correct one-word substitution – Ordnance:
• Ordnance means military weapons and ammunition, and in broader usage it also includes military stores/equipment used in warfare.
• (Hindi meaning: सैन्य हथियार व गोला-बारूद / युद्ध सामग्री)
• Example: The army depot stored ordnance and other essential supplies.
• Meanings of other options (why they are incorrect):
• (b) Panoply – a complete or impressive collection of things; also a suit of armour (Hindi: विविध/सम्पूर्ण संग्रह; कवच)
• यह सामान्य संग्रह दर्शाता है; विशेष रूप से military supplies का standard one-word नहीं है।
• (c) Booty – stolen goods; loot taken in war (Hindi: लूट का माल)
• यह supplies नहीं, बल्कि लूटा गया सामान है।
• (d) Accouterment – additional equipment/clothing items; accessories (Hindi: साज-सामान / उपकरण)
• यह general accessories/equipment है, विशेष रूप से weapons-ammunition नहीं।
So the correct answer is (a).
