Hint :To answer this question, we first need to understand what is ore. The majority of metals are too reactive to exist in the earth on their own. Instead, they exist as ores, which are compounds made up of other elements. Metals are made from ore, which is a raw material. Individual crystals of minerals are made up of unit cells or basic unit layers of two or more types. Minerals are inorganic catalysts that operate as metabolic regulators in the human body.

Complete Step By Step Answer:
Silver – Silver is a chemical element with atomic number 47 and the symbol Ag (from the Latin argentum, derived from the Proto-Indo-European). It is a glossy, soft, white transition metal with the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. [requires citation] The metal can be found in its pure, elemental form ("native silver") in the Earth's crust, as an alloy with gold and other metals, and in minerals like argentite and chlorargyrite. The majority of silver is created as a byproduct of the refining of copper, gold, lead, and zinc.
Argentine – In mineralogy, argentite is cubic silver sulphide (from the Latin argentum, silver). When it cools to room temperature, it transforms into acanthite, a monoclinic polymorph. The International Mineralogical Association has ruled that argentite is not a legitimate mineral.
Horn silver – The mineral form of silver chloride is chlorargyrite (AgCl). In the oxidation of silver mineral deposits, chlorargyrite forms as a secondary mineral phase. It has an isometric - hexoctahedral crystal structure. It has also been found as colorless to variably yellow cubic crystals, which are often large to columnar in appearance.
Pyrargyrite – Pyrargyrite is a silver sulfantimonite-based sulfosalt mineral. It's also known as ruby silver or dark red silver ore, and it's a valuable source of the metal. It is isomorphous with the equivalent sulf arsenide known as prostitute or light red silver ore and is closely related to it. Georg Agricola mentioned ruby silver or red silver ore in 1546, but the two species are so similar that chemical studies of both were needed to tell them apart.
So, we conclude that chemical formulas of the ores are-
Argentine – $ A{g_2}S $
Horn silver – $ AgCl $
Pyrargyrite – $ AgSb{S_2} $
So, the final answer is option (A) $ A{g_2}S,AgCl{\kern 1pt} {\kern 1pt} {\kern 1pt} and{\kern 1pt} {\kern 1pt} AgSb{S_2} $ .

Note :
Ore is a type of natural rock or silt that includes one or more precious minerals, usually metals, that may be mined, processed, and sold for profit. Mining extracts ore from the earth, which is then treated or processed, usually by smelting, to remove the valuable metals or minerals.
