The correct answer is option 2 which correctly matches the committees with their corresponding chairperson.

I - Disinvestment of shares in Public Sector Enterprises was chaired by C. Rangarajan, thus matching with option D in List II.

II - Industrial Sickness was chaired by Onkar Goswami, thus matching with option B in List II.

III - Tax Reforms Committee was chaired by Raja Chelliah, thus matching with option A in List II.

IV - Reforms in Insurance Sector was chaired by R.N. Malhotra, thus matching with option C in List II.

Alternately,

Option 1 has incorrect mismatches for I (Disinvestment of shares in Public Sector Enterprises) and III (Tax Reforms).

Option 3 also has incorrect matches for I, II (Industrial Sickness) and IV (Reforms in Insurance Sector).

In option 4, all four committees are matched with the wrong chairpersons. Therefore, option 2 is the correct answer.
