The correct answer is: a) India, Britain, and Japan
The Battle of Imphal and Kohima was a major battle in the Second World War that took place in northeastern India from March to July 1944. The battle was fought between the British Indian Army and the Imperial Japanese Army. The Japanese army had invaded India in an attempt to capture the strategically important city of Imphal. The British Indian Army, supported by the United States Army Air Forces, defended Imphal and Kohima, and eventually defeated the Japanese army.
