Correct answer

B. ( a ) ‐ ( i ) , ( b ) ‐ ( ii ) , ( c ) ‐ ( iv ) , ( d ) ‐ ( iii )

Step-by-step solution

The oil drop experiment was to measure the specific charge of an electron. Davisson & Germer experiment proved the wave nature of electrons. Rutherford experiment proved the presence of a nucleus, while the Franck-Hertz experiment established the Quantisation of energy levels.
