The correct answer is the first option which states that Moplah revolt occurred in Kerala, the Pabna revolt in Bengal, the Eka Movement in Awadh, and the Birsa Munda revolt in Bihar.

Here`s why:

Option 1: The correct association is made in I-A (Moplah revolt - Kerala), II-C (Pabna revolt - Bengal), III-D (Eka Movement - Awadh) and IV-B (Birsa Munda revolt - Bihar).

Option 2: This choice incorrectly places the Moplah revolt in Bihar, the Pabna revolt in Bengal which is correct, Eka Movement in Awadh which is correct, but the Birsa Munda revolt in Kerala which is incorrect.

Option 3: This option also incorrectly pairs Moplah revolt with Kerala (which is correct), Pabna revolt with Bihar, Eka Movement with Bengal, and Birsa Munda revolt with Awadh.

Option 4: This selection incorrectly associates the Moplah revolt with Bengal, the Pabna revolt with Awadh, the Eka Movement with Kerala, and the Birsa Munda revolt with Bihar. This option has only the location of the Birsa Munda revolt correct.
