To answer this question, the user must have knowledge about Gandhiji and his life experiences.
The answer is:
A. Harishchandra
Explanation:
Gandhiji was deeply influenced by the character of Harishchandra when he saw a play on his life. Harishchandra is a mythological character who is known for his truthfulness and unwavering commitment to righteousness. Gandhiji saw a play on Harishchandra's life when he was a young boy and was deeply moved by the character's devotion to truth and justice. This played an important role in shaping Gandhiji's own values and beliefs, and he often referred to Harishchandra as his ideal throughout his life.
B. Vikramaditya - Vikramaditya is also a mythological character, but there is no evidence to suggest that Gandhiji was particularly impressed by him.
C. Ashoka - Ashoka is a historical figure who is known for his transformation from a ruthless conqueror to a compassionate ruler. While Gandhiji was certainly inspired by Ashoka's message of non-violence and tolerance, there is no evidence to suggest that he was particularly impressed by him as a mythological character.
D. Krishna - Krishna is a popular mythological character who is revered by many in India, but there is no evidence to suggest that Gandhiji was particularly impressed by him. While Gandhiji certainly believed in the message of non-attachment and selflessness that Krishna preached in the Bhagavad Gita, he did not place any one mythological character above all others.
