The correct answer is option 4: Gujarat. Mahatma Gandhi, also known as Mohandas Karamchand Gandhi, was born on October 2, 1869, in the town of Porbandar, Gujarat, which is a state in western India. Porbandar was part of the region known as Kathiawar at the time of Gandhi`s birth. It is important to note that Madhya Pradesh, Assam, and Rajasthan, mentioned in options 1, 2, and 3 respectively, are all different states in India, but they are not the birthplace of Mahatma Gandhi.
