Which of the following pairs is/are correctly matched? 1. Continental Drift : Edwin Hubble 2. Expansion of Universe : Alfred Wegener 3. Photoelectric Effect : Albert Einstein Select the correct answer using the code given below :

1. Evaluating the pairs for correct matching: 2. Pair 1: Continental Drift theory was proposed by Alfred Wegener, not Edwin Hubble. Hubble is known for discovering the Expansion of Universe. Incorrectly matched. 3. Pair 2: Expansion of Universe was discovered by Edwin Hubble based on observations of galactic redshifts, not proposed by Alfred Wegener. Incorrectly matched. 4. Pair 3: The Photoelectric Effect (emission of electrons when light shines on a material) was experimentally observed earlier, but Albert Einstein provided the theoretical explanation in 1905, proposing that light consists of quanta (photons), for which he received the Nobel Prize. Correctly matched. 5. Only pair 3 is correctly matched.
