The correct answer is option 3, Germany. Subhas Chandra Bose started the ‘Azad Hind Radio’ in Germany.

Option 1, Japan, is not the correct answer because although Subhas Chandra Bose had allies in Japan during World War II, it was in Germany that he started the ‘Azad Hind Radio’.

Option 2, Austria, is also not the correct answer because Subhas Chandra Bose did not start the ‘Azad Hind Radio’ in Austria.

Option 4, Malaysia, is not the correct answer either. While Subhas Chandra Bose was active in Southeast Asia during World War II and had support from the Indian community there, the ‘Azad Hind Radio’ was not started in Malaysia.

Therefore, the correct answer to the question is option 3, Germany. It was in Germany that Subhas Chandra Bose started the ‘Azad Hind Radio’ during World War II.
