Calamine and Siderite are Carbonate Ores:
- Calamine is a mineral composed of zinc carbonate (ZnCO3), and it is an important ore of zinc. It is typically found in association with sphalerite (zinc sulfide) in zinc deposits.
- Siderite is an iron carbonate mineral (FeCO3) and is one of the main ores of iron. It is commonly found in sedimentary rocks and is often associated with other iron-rich minerals such as magnetite and hematite.

Argentite and Cuprite are Oxides:
- Argentite is a silver sulfide mineral (Ag2S) and is the most important ore of silver. It is a dark gray to black mineral that occurs in hydrothermal veins and is often associated with other silver-bearing minerals such as acanthite and native silver.
- Cuprite is a copper oxide mineral (Cu2O) and is a major ore of copper. It is a deep red mineral that forms in the oxidized zones of copper ore deposits. Cuprite is often found in association with other copper minerals such as malachite and azurite.

Zinc Blende and Pyrites are Sulphide Ores:
- Zinc blende, also known as sphalerite, is a zinc sulfide mineral (ZnS) and is the most important ore of zinc. It is a common mineral found in many ore deposits and is often associated with other sulfide minerals such as galena (lead sulfide) and chalcopyrite (copper iron sulfide).
- Pyrites, also known as iron pyrite or fool's gold, is an iron sulfide mineral (FeS2). While it is not a significant ore of iron, it is often associated with other valuable minerals such as gold and copper. Pyrite is commonly found in sedimentary rocks and hydrothermal veins.

Malachite and Azurite are Ores of Copper:
- Malachite is a copper carbonate hydroxide mineral (Cu2CO3(OH)2) and is a secondary ore of copper. It is typically found in the oxidized zones of copper ore deposits and often occurs as botryoidal (grape-like) or stalactitic masses with vibrant green coloration.
- Azurite is a copper carbonate mineral (Cu3(CO3)2(OH)2) and is another secondary ore of copper. It forms in the oxidized zones of copper deposits and is often found in association with malachite. Azurite has a deep blue color and is prized for its aesthetic value in jewelry and art.

In summary, the correct statements are:
a) Calamine and siderite are carbonate ores.
c) Zinc blende and pyrites are sulphide ores.
d) Malachite and azurite are ores of copper.
