Match List-I with List-II:

List-I List-II
A J.J. Thomson I Oil drop method for charge
B R.A. Millikan II Discovery of neutron
C James Chadwick III Measurement of \( e/m_e \) ratio
D Ernest Rutherford IV Nuclear model of atom

Choose the correct answer from the options given below:

  1. A-(II), B-(IV), C-(III), D-(I)

  3. A-(IV), B-(II), C-(I), D-(III)
  4. A-(III), B-(I), C-(II), D-(IV)

Correct answer · Option 4

A-(III), B-(I), C-(II), D-(IV)

Explanation

Thomson measured \( e/m_e \), Millikan measured charge via oil drop, Chadwick discovered neutrons, and Rutherford proposed the nuclear model.
