From the given: 'prot' appears in both 'my India' and 'India won', so prot = India. 'polo' is used in 'base ball' and has no link to India or Radio. 'All India Radio' needs three words: one new word for 'All', 'prot' for 'India', and another new word for 'Radio'.
Option 2: 'Kud prot nid' has two new words (Kud = All, nid = Radio) with prot = India. This fits.
