Match the items in Column I with its main use listed in Column II: Column I Column II A. Silica gel i. Transistor B. Silicon ii. Ion-exchanger C. Silicone iii. Drying agent D. Silicate iv. Sealant

Options

  1. AA - iii, B - i, C - iv, D - ii
  2. BA - iv, B - i, C - ii, D - iii
  3. CA - ii, B - i, C - iv, D - iii
  4. DA - ii, B - iv, C - i, D - iii

Correct answer

A. A - iii, B - i, C - iv, D - ii

Step-by-step solution

Silica gel is used as a drying agent. Silicon is used in Transistors. Silicone is a sealant while silicates including Zeolites are ion exchangers.
