The correct answer is: a) Lead and Zinc.
Lead and zinc are two of the most common metals found in the Earth’s crust. They are both used in a variety of industrial applications, including batteries, electronics, and construction. Lead is also used in ammunition and radiation shielding. Zinc is used in galvanizing steel, which helps to prevent corrosion.
Minor occurrences of lead and zinc have been reported in Mizoram. The most significant deposit is located in the Saitual district. The deposit is estimated to contain about 1 million tons of lead and 2 million tons of zinc.
The other options are incorrect because they are not common minerals found in Mizoram. Silver and platinum are both precious metals that are used in jewelry and other high-value applications. Titanium and zirconium are both industrial metals that are used in a variety of applications, including aerospace, automotive, and medical devices. Beryllium and lithium are both rare metals that are used in a variety of applications, including electronics, batteries, and nuclear power.
